In the specific working process of the first embodiment, because the two lifting mechanisms lift simultaneously, when a traditional vibration sensor is used for detecting whether the sensor signal is abnormal due to the fact that the lifting mechanisms are jammed, the signals of the two sensors respectively close to the supporting positions below the continuous rolling bags to be cut are used for carrying out logical AND operation, or one sensor is used for carrying out vibration amplitude whether the amplitude is the amplitude or half of the amplitude (the signals respectively correspond to the superposition of the signals generated when the two lifting mechanisms are normal and simultaneously or only one vibration signal reflected when the lifting mechanisms work normally), so that the sensitivity of the sensor is required to be higher, the subsequent threshold value comparison is required, and the calibration of the threshold value and the subsequent comparison and calculation process are troublesome. In addition, in the first implementation, because the two lifting mechanisms and the transmission mechanism are positioned at the same side of the first base/the second base, the generated vibration easily causes the whole device to shift in the taking process, and larger unnecessary vibration is easily generated even if a fixing means is adopted at the corresponding side; in addition, a card machine is arranged at one lifting mechanism, so that follow-up shutdown maintenance of the two lifting mechanisms is inevitably required, and therefore before the working personnel arrive at the station, the other lifting mechanism cannot work normally, and partial working efficiency is reduced.
In view of the above technical drawbacks, this embodiment changes the relative installation positions of the first and second lifting mechanisms 2 and 5 and the driving mechanism 9, adds a vibration sensor and a proximity switch sensor, defines the initial installation positions of the first driving rod and the second driving rod on the transmission shaft 401, adds a double-end rotating motor electronic clutch design that allows independent control of the rotation and stop of the two driving rods 4, and adds an auxiliary design that is fixed in accordance with the initial starting position of one of the driving rods. Thereby make and cut the in-process whole device vibration and reduce, and can utilize a vibration sensor just can be fine realization cut any one of in-process two elevating system can in time reliably early warning when the card machine to break off faulty electronic clutch, thereby when realizing independent maintenance, keep another elevating system's effective work, the maximize guarantees production efficiency.
The specific working process is as follows: under normal operating condition, two electronic clutches at both ends of the double-end rotating motor rotating shaft are opened, so that two driving rods are controlled to rotate simultaneously, because the phase difference of the initial installation positions of the first driving rod and the second driving rod on the two transmission shafts 401 is 180 degrees (for example, when the driving rods can be installed, one driving rod is located at 12 o 'clock position in a pointing mode, and the other driving rod is located at 6 o' clock position in a pointing mode), so that the rotating phases of the two first driving rods and the second driving rod are different by half a circle, one cutting knife 3 is in a rotating period, the other cutting knife is in a non-cutting state, so that the two times of cutting occur in the same rotating period, and the two times of cutting occur and differ by half the rotating period, wherein the rotating period and the rotating shaft rotating speed passing through the motor can be converted. This design makes only one cutter take place to cut the action at the same moment, corresponds same moment and can only produce a vibration signal, consequently only need judge after current vibration signal appears, appears the vibration signal of second time after predetermined half rotation cycle time moment and can regard as normally working, and this design is to the monitoring accuracy requirement greatly reduced of vibration sensor because the contrast only is that the emergence moment of adjacent sensing signal is enough to satisfy the requirement. If the second vibration signal does not appear after the preset half rotation period time after the last vibration signal appears, the phenomenon of jamming of the lifting mechanism can be considered to exist, which lifting mechanism is jammed is judged by the following specific judgment method, then the electronic clutch driving the driving rod of the lifting mechanism is closed, and only the driving rod on the normal side is kept to be driven to rotate normally.
The process of which one of the two lifting mechanisms is blocked is realized by means of a vibration sensor signal and an auxiliary design that a proximity switch sensor is arranged on one side surface of the first base 1 at the same height with the two transmission shafts 401 and in the rotating range area of the driving rod 4 as follows: firstly, the double-end rotating motor is supposed to keep the same rotating direction unchanged in the whole operation process, which also accords with the setting habit and the requirement of the conventional working condition in most normal operations; taking the left lifting mechanism in the attached drawing 1 as an example, the rotation direction is counterclockwise rotation, a proximity switch sensor is arranged on the mounting side surface of the first base 1 corresponding to one of the lifting mechanisms, after the double-end rotating motor runs for the first time and stops working for each subsequent time, the driving rod 4 in the lifting mechanism on the side is ensured to stay to cover the proximity switch sensor and be in a horizontal state with the same height as the transmission shaft 401 (the stay position can be determined by the aid of signals of the proximity switch sensor), the arrangement enables the cutting knife on the mounting side of the proximity switch sensor to be cut after 3/4 rotation cycles, the cutting knife on the other side to be cut for the first time after 1/4 cycles, therefore, the vibration signals of the first and odd orders (1/3/5 … …) correspond to the normal cutting action of the cutting knife on the other side, the vibration signals corresponding to the even-numbered sequence are normal cutting actions of the cutting knife on the installation side of the proximity switch sensor at present, so that the vibration sensor signals only need to be counted, and the lifting mechanism on which side is in fault can be judged according to the parity of the counting corresponding to the vibration signals which should be present but not present.
In the embodiment, the quick discrimination of the lifting mechanism on the card machine side is obtained by utilizing the counting of the signal of one vibration sensor and matching with the auxiliary design of the initial starting position fixing of one driving rod, and the driving rod on the card machine side can be quickly separated and rotated by matching with an electronic clutch, so that the normal work of the other lifting mechanism and the cutting knife is ensured. In addition, the two lifting mechanisms, the driving rods and the cutting knives are respectively positioned on two side surfaces of the first base 1, the double-end rotating motor is clamped in the middle, and the stress is balanced, so that the base deviation and the vibration caused in the working process of the two lifting mechanisms can be reduced to the maximum extent.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
