Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
As shown in fig. 1, the printer in the present embodiment includes a casing, a paper pickup mechanism 1, an image forming apparatus, and a paper detection sensor provided at a paper feed position of the paper pickup mechanism 1. The paper rubbing mechanism, the paper picking mechanism 1 and the imaging device can all adopt corresponding structures in the existing printer. The paper feeding process of the printer is generally that the paper rubbing mechanism is controlled to work firstly so as to rub paper in the paper box to move, when the paper reaches the paper feeding position of the paper picking mechanism 1, the paper detection sensor is triggered, and then the paper picking mechanism 1 is controlled to start working in advance based on the trigger signal of the paper detection sensor, so that the rotating speed of the paper picking mechanism 1 is stabilized at the set paper picking speed when the paper reaches the position of the paper picking mechanism 1. The paper rubbing mechanism continues to drive the paper, and when the front end of the paper reaches the paper picking mechanism 1, the paper picking mechanism 1 starts to drive the paper to continue to advance. Then, the image forming apparatus is started at a time of a set period from the start of picking up the paper, and a preset image is printed on the paper. Based on the difference of the paper and some fixed influences of the internal structure of the printer, the actual paper picking speed of the paper by the paper picking mechanism 1 and the set paper picking speed may be different, so that the starting time of the imaging device needs to be adjusted, and the problem that the image printed on the paper shifts upwards or downwards is avoided. In general, if the actual paper pickup speed is faster than the set paper pickup speed, the image forming apparatus is turned on at the timing set as it is, which causes a problem of downward movement of the image, and conversely, a problem of upward movement of the image. In addition, the paper is inevitably skewed left and right during the paper picking process.
The driving lever 2 is rotatably arranged on the shell, the driving lever 2 is arranged corresponding to the paper detection sensor and can trigger the paper detection sensor along with the paper action, if a trigger piece is arranged on the driving lever 2, after the paper touches the driving lever 2, the paper moves under the driving of the paper rubbing mechanism, and then the driving lever 2 is driven to swing upwards, so that the trigger piece on the driving lever 2 triggers the paper detection sensor, the paper detection sensor acquires a paper starting point signal, and at the moment, the paper picking mechanism 1 can be controlled to start paper picking according to the paper starting point signal. When the paper completely passes through the position of the deflector rod 2, the deflector rod 2 swings down, so that the trigger of the paper detection sensor is released, and the paper end point signal can be obtained. The whole paper passing process can be effectively known through the paper starting point signal and the paper ending point signal.
In this embodiment, the baffle 3 is further rotatably connected to the casing, the baffle 3 extends along the left-right direction and is fixed on a shaft lever 4, two ends of the shaft lever 4 are rotatably limited on the casing, and further the baffle 3 is rotatably connected to the casing. The deflector rod 2 is arranged on the baffle plate 3, so that the structure is simplified. In addition, in order to ensure that the paper can reliably contact the deflector rod 2, the deflector rod 2 is arranged at the middle position in the left-right direction of the baffle plate 3.
When the paper moves to the position of the baffle plate 3, because the movement of the paper has certain movement inertia, in the embodiment, after the front end of the paper collides with the baffle plate 3, the paper rubbing mechanism is controlled to be suspended, so that the paper can automatically realize the left-right skew correction under the action of the baffle plate 3 based on the movement inertia of the paper, and the left-right skew problem of the paper is effectively improved. When the pause time of the paper rubbing mechanism reaches the set time T2, the paper rubbing mechanism is controlled to work, then the push plate is pushed to swing upwards by the paper based on the driving force of the paper rubbing mechanism, and meanwhile the deflector rod 2 is driven to swing upwards, so that the paper starting point signal is acquired by triggering the paper detection sensor based on the deflector rod 2. The paper picking mechanism 1 is controlled to work based on the paper starting point signal, and the rotating speed of the paper picking mechanism 1 can reach a set speed in the time when the paper moves from the position of the baffle 3 to the position of the paper picking mechanism 1, so that the paper is driven to move continuously by the driving of the paper picking mechanism 1. After the tail end of the paper leaves the position of the baffle plate 3, the baffle plate 3 and the deflector rod 2 synchronously swing down, trigger on the paper detection sensor is released, and then a paper end signal is obtained.
In this process, in order to ensure that the paper rubbing mechanism drives the paper to swing up synchronously with the deflector 3 and the deflector 2, the quality on the deflector 3 cannot be too high, and in order to reduce the quality of the deflector 3, the normal paper picking action is ensured, and in this embodiment, the deflector 3 includes a plurality of plates arranged at intervals, and the plates are fixed on the shaft lever 4 in a manner of being arranged in the left-right direction. In order to avoid blocking normal paper travelling, the plate body is bent and extended from top to bottom in the paper travelling direction, the deflector rod 2 is also bent and extended from top to bottom in the paper travelling direction, the extending direction of the plate body and the deflector rod 2 conforms to the paper feeding direction, the paper travelling is not blocked, and the paper feeding smoothness is ensured.
The printer can adopt the following paper feeding correction method to solve the problem of up-and-down offset of the image in the printing process and improve the printing effect.
As shown in fig. 2, the paper feeding correction method includes: after the print job is started, the sheet start signal and the sheet end signal are detected by the aforementioned sheet detection sensor.
And calculating the actual paper picking time T1 according to the detected and acquired paper starting point signal and paper ending point signal. Specifically, the paper rubbing action is controlled, when the paper reaches the position of the deflector rod 2, the deflector rod 2 is driven to swing upwards based on the driving of the paper rubbing mechanism, the deflector rod 2 triggers the paper detection sensor, and then a paper starting point signal is acquired, and when the paper starting point signal is acquired, a time point K1 corresponding to the acquired paper starting point signal is recorded. And controlling to perform paper picking according to the paper starting point signal, and after paper picking is started, controlling the imaging device to start working after a specific time length A, so as to print images on paper. The duration A is Ts or T, when the printing work of the first paper sheet after the printer is started is carried out, the duration A adopts Ts, and the printing work of the subsequent paper sheet adopts T.
After the tail end of the paper passes through the position of the deflector rod 2, the deflector rod 2 is released to swing down, then the trigger of the paper detection sensor is released, and then the paper end signal can be obtained, and when the paper end signal is obtained, the time point K2 corresponding to the paper end signal is recorded. Then, the actual pickup time t1=k2-K1 of the current sheet is calculated.
Since the length of the paper is fixed and the set paper pickup speed of the printer is also fixed, the theoretical paper pickup time t0=l/V0 can be calculated from the current length L of the paper and the set paper pickup speed V0 of the paper pickup mechanism 1.
In the paper picking process, the actual paper picking speed is different from the theoretical paper picking speed possibly caused by paper or other structural factors, and further the difference of paper picking time is caused, so that the starting time point of the imaging device in the next printing work is determined based on the time difference of T1 relative to T0, the up-down offset adjustment of the printed image is further realized, the up-down offset problem of the printed image is solved, and the printing effect is improved.
Specifically, the starting time point of the imaging device at the next printing work is calculated as the time point with the time length of T after the paper starting point signal is acquired, wherein T=Ts-T, and t=T0-T1; wherein Ts is the initial time length after the start point signal of the paper is acquired from the set start time point distance of the imaging device.
According to the paper feeding correction method, the influence of the actual paper picking speed is judged through the time difference between the actual paper picking time and the theoretical paper picking time, and the starting time point of the imaging device is adjusted based on the time difference, so that the starting time point of the imaging device can be effectively matched with the actual paper picking speed. And the calculation is relatively simple by adjusting the starting time point of the imaging device, the adjustment control is more timely and accurate, and the adjustment method is more accurate and can better and more accurately solve the problem that the printed image is offset up and down relative to the uncontrollable influence factors in the adjustment of the paper picking speed.
