Further, referring to fig. 2, as an embodiment of the automatic waste discharge method provided by the present invention, step S1-4 includes the following steps:
the control center controls the waste paper collecting device to be in a working state, and judges whether a second pulse of the second photoelectric sensor is received or not, and if the second pulse is received, the current printed paper does not depart from the conveying device; if the second pulse is not received, the current printed paper leaves the conveying device.
Through the steps, the control center can more accurately judge whether the unqualified printed paper is separated from the conveying device through the second photoelectric sensor.
Referring to fig. 1 and 5, the present invention further provides a non-stop waste discharging method, which will now be described. A non-stop waste discharge method comprises the following steps:
s4-1: sequentially placing a plurality of printed paper on a conveying device of an automatic waste discharge device, wherein the conveying device drives the printed paper to sequentially pass through a visual inspection device, a second photoelectric sensor and a waste paper collecting device of the automatic waste discharge device;
s4-2: sequentially checking whether all the printed paper on the conveying device is qualified or not through the visual checking device, and if the printed paper is unqualified currently, sending a control signal corresponding to the printed paper currently to a control center of the automatic waste discharge device;
s4-3: the control center judges whether the current printed paper moves to a used paper collecting device of the automatic waste discharge device according to the control signal and a second pulse of the second photoelectric sensor, and when the control center judges that the current printed paper moves to the used paper collecting device, the control center controls the used paper collecting device to be in a working state;
s4-4: the control center judges whether the current printed paper is separated from the conveying device, and if the current printed paper is separated from the conveying device, the control center controls the used paper collecting device to be in a standby state.
Compared with the control center which directly judges whether the printed paper moves to the waste paper collecting device through the visual inspection device, the control center can judge whether the printed paper moves to the waste paper collecting device through the visual inspection device and the second photoelectric sensor. The user can directly separate the unqualified printed paper from the conveying device without stopping the conveying device. By the non-stop waste discharge method, ten thousand printed paper sheets can be quickly checked every hour, unqualified printed paper sheets in the ten thousand printed paper sheets can be taken out, and the quantity and the efficiency of checking the printed paper sheets are greatly improved. And meanwhile, the waste paper collecting device can not influence qualified printed paper in the using process.
Further, referring to fig. 5, as a specific embodiment of the non-stop waste discharge method provided by the present invention, the control signal includes first total data and non-conforming data, the control center obtains the first total data through a first pulse of a first photosensor of the vision inspection apparatus, and the control center obtains the non-conforming data through a processing center of the vision inspection apparatus;

Whether the current printed paper moves to the waste paper collecting device of the automatic waste discharge device is rapidly calculated through the first total data and the second pulse, so that the control center can accurately judge whether the current printed paper moves to the waste paper collecting device of the automatic waste discharge device.
Specifically, the first total number data and the fail data are set as integer data.
Further, referring to fig. 5 and 6, as an embodiment of the method for discharging waste without shutdown according to the present invention, S4-3 includes the following steps:
s5-1: the control center calculates to obtain real-time second total data according to the second pulse;
s5-2: the control center judges whether the first total data is equal to the second total data, if the first total data is equal to the second total data, the current printed paper moves to the waste paper collecting device, and the control center controls the waste paper collecting device to be in the working state.
The control center counts according to the second pulse through steps S5-1 to S5-2 to calculate the total number of printed sheets passing through the second photosensor, thereby judging whether the current printed sheet is moved to the used paper collecting device according to the total number of printed sheets passing through the first photosensor and the total number of printed sheets passing through the second photosensor.
Specifically, the second total number data is set as integer data.
Further, referring to fig. 5 and fig. 7, as an embodiment of the non-stop waste discharging method provided by the present invention, before step S4-1, the method further includes the following steps:

the control center divides the total number of the first pulses by the number data to obtain first total number data;
step S5-1 is set to:
and the control center divides the total number of the second pulses by the number data to obtain second total number data.
Because the printed sheets are different in size, when one printed sheet passes through the first photosensor, the number of first pulses generated by the first photosensor to the control center is one or more. The number data is the number of first pulses generated by a printed paper passing through the first photoelectric sensor and sent to the control center, and the user sets the number according to the size of the printed paper. The first total number data is a total number of printed sheets passing through the first photosensor.
Because the printed sheets are different in size, when one printed sheet passes through the second photosensor, the number of second pulses generated by the second photosensor to the control center is one or more. The second total data is the total number of printed sheets passing the second photosensor.
Specifically, the number data is set as integer data.
Further, referring to fig. 7, as an embodiment of the non-stop waste discharging method provided by the present invention, in step S6-1, the method includes the following steps:
s6-1-1: controlling a zero clearing button of the automatic waste discharge device to clear the number data, and placing a counting paper on the conveying surface of the conveying device;
s6-1-2: starting a first photoelectric sensor of the conveying device and the automatic waste discharge device, enabling the counting paper to pass through the first photoelectric sensor, and enabling the counting button to be in a first pressing state;
s6-1-3: when the counting paper completely passes through the first photoelectric sensor, controlling the counting button to be in a second pressing state;
s6-1-4: and the control center calculates the number data according to the first pulse of the first photoelectric sensor.
The number data is manually determined, the number data can be reset and reset, and a user can set the number data according to printed paper with different sizes. The number data is set through the counting button, and the operation is convenient. The actual size of the counting paper is selected according to the actual size of the printed paper, and the counting paper plays a role in simulating the printed paper.
