The mode of carrying first magazine 81 to elevating platform 51 has the multiple, if can place first magazine 81 in elevating platform 51 through the arm, can place first magazine 81 in the upgrading platform through artificial, perhaps through transfer chain with magazine upset and elevating platform 51 etc. do not do specific restriction here, only need can place first magazine 81 in elevating platform 51 can. For example, when the first magazine 81 is placed on the lifting table 51 by a mechanical arm, the mechanical arm places the first magazine 81 on the lifting table 51 and then sends a trigger signal, and the controller obtains the trigger signal of the mechanical arm and controls the lifting table 51 to move to the first clamping position according to the trigger signal of the mechanical arm. There are various ways to control the lifting platform 51 to stop after moving to the first clamping position, for example, the time for the lifting platform 51 to move to the first clamping position is determined according to the distance between the lifting platform 51 and the first clamping position divided by the moving speed of the lifting platform 51, or a position sensor capable of acquiring the position in real time is arranged on the lifting platform 51, or a limit sensor and the like can be arranged on the first clamping position, and no specific limitation is required here, and only the lifting platform 51 can be determined to reach the first clamping position. For example, when the time for the lifting platform 51 to move to the first clamping position is determined by dividing the distance between the lifting platform 51 and the first clamping position by the moving speed of the lifting platform 51, the controller calculates the time for the lifting platform 51 to move to the first clamping position, and controls the lifting platform 51 to move toward the first clamping position according to the time calculated by the controller, and controls the lifting platform 51 to stop when the time reaches the calculated time. The controller is of the chip type.
When the first power part 23 is controlled to clamp the first material box 81, the first material box 81 can be clamped according to the stop signal of the lifting table 51, or the first material box 81 can be determined to the first clamping position by the position sensing arranged on the first clamping position, and the like, and the first material box 81 can be confirmed to reach the first clamping position without specific limitation. For example, when it is determined that the first magazine 81 is located at the first clamping position in a manner that the signal triggered when the lifting table 51 stops is the signal to the first clamping position, the controller controls the first power member 23 to clamp the first magazine 81, so that the first clamping position achieves the purpose of clamping the first magazine 81. After the first power member 23 is controlled to clamp the first magazine 81, the clamping of the first magazine 81 by the first clamping position may be confirmed, or may not be confirmed. The mode of confirming first centre gripping position centre gripping first magazine 81 has the multiple, if through set up pressure sensor on the centre gripping position, perhaps detect first centre gripping position centre gripping first magazine 81 through setting up the subassembly of making a video recording and can also confirm etc. through artificial mode, do not do specific restriction here, only need can confirm first centre gripping position can the centre gripping first magazine 81.
When the first clamping position and the second clamping position are switched, the position exchange of the first clamping position and the second clamping position can be determined in a limiting mode through the limiting part 29, the position exchange of the first clamping position and the second clamping position can also be confirmed through the angle sensor, and the like. For example, when the positions of the first clamping position and the second clamping position are determined to be aligned by means of the limiting member 29, the limiting protrusion 28 for limiting is disposed on the rotating plate 21, and the limiting member 29 abutting against the limiting protrusion 28 is disposed on the mounting block 1, so that after the positions of the first clamping position and the second clamping position are aligned, the limiting protrusion 28 can abut against the limiting member 29 for limiting. After the positions of the first clamping position and the second clamping position are exchanged, the first material box 81 is located above the second material box 82, and the material falls from the first material box 81 to the second material box 82 under the action of gravity, so that the purpose of exchanging the material from the first material box 81 to the second material box 82 is achieved.
After the materials are exchanged, the lifting table 51 needs to be controlled to place the second material box 82 in the second clamping position at the first material conveying end 41, and when the second material box 82 is placed at the first material conveying end 41, the lifting table 51 needs to be controlled to be located at the lower side of the second clamping position, so that when the second material box 82 is loosened at the second clamping position, the lifting table 51 can support the second material box 82. When the second magazine 82 is received by the elevating platform 51, the elevating platform 51 delivers the second magazine 82 to the first delivery end 41. When the lifting platform 51 moves to the first material conveying end 41, the second material box 82 can be placed at the first material conveying end 41 by arranging a notch for the lifting platform 51 to pass through at the first material conveying end 41, or the material box can be placed at the first material conveying end 41 by inclining the lifting platform 51, and no specific limitation is imposed on the material box, and only the second material box 82 needs to be placed at the first material conveying end 41. For example, the length of the lifting platform 51 needs to be smaller than the length of the second material box 82, and meanwhile, the first material conveying end 41 is provided with a notch, and the size of the notch only needs to be enough for the lifting platform 51 to pass through, so that when the lifting platform 51 enters the notch, the second material box 82 can be placed at the first material conveying end 41, and the purpose of placing the second material box 82 at the first material conveying end 41 is achieved.
An in-position sensor configured to detect that the first magazine 81 reaches the first clamping position is provided corresponding to the first clamping position; before the step of controlling the first power member 23 to clamp the first magazine 81, the method further comprises: and acquiring position information of the first material box 81 of the in-place sensor, determining that the first material box 81 is located at a first clamping position, and controlling the first power part 23 to clamp the first material box 81.

The in-place sensor may be a photoelectric switch sensor, an inductive proximity sensor, an ultrasonic sensor, or the like, and is not particularly limited herein, and only the first magazine 81 is sensed to reach the first clamping position. For example, when the in-place sensor is an inductive proximity sensor, the inductive proximity sensor is disposed in the first clamping position, and when the first magazine 81 reaches the first clamping position, the inductive proximity sensor detects the first magazine 81, the inductive proximity sensor obtains position information of the first magazine 81 and sends out the position information of the first magazine 81, and when the controller obtains the position information of the first magazine 81 sent by the inductive proximity sensor, the lifting table 51 is controlled to stop lifting. The in-place sensor is arranged in the first clamping position, so that foreign matter blocking can be avoided, and the clamping accuracy of the first clamping position can be improved.
