Referring to fig. 2 and 3, the deviation rectifying mechanism 400 of the present embodiment includes a driving assembly 420, a first guide 421 and a second guide 422 movably disposed in the conveying channel 310, and the first guide 421 and the second guide 422 are disposed at intervals along the width direction of the conveying channel 310, and a deviation rectifying channel 410 is formed between the first guide 421 and the second guide 422; the driving assembly 420 is in communication connection with the control device 200, and the first guide 421 and the second guide 422 are both in transmission connection with the driving assembly 420, the driving assembly 420 is used for driving the first guide 421 and the second guide 422 to be close to or far away from each other so as to adjust the width of the deviation rectifying channel 410, that is, the driving assembly 420 can be controlled by the control device 200 to drive the first guide 421 and the second guide 422 to move so as to adjust the width of the deviation rectifying channel 410 formed between the first guide 421 and the second guide 422, so that the width of the deviation rectifying channel 410 can be adjusted to be the first width or the second width.
The driving assembly 420 may be selected according to the need, and the driving assembly 420 of this embodiment includes two rack and pinion transmission assemblies, which are respectively connected with the first guide 421 and the second guide 422 in a transmission manner; in other embodiments, the drive assembly 420 may also include a conveyor belt assembly, a screw drive assembly, and the like.
The first guide 421 and the second guide 422 may be guide bars, guide plates, or the like, and are not particularly limited herein.
Referring to fig. 3, the driving assembly 420 is disposed on the channel plate 320; the channel plate 320 is provided with two movable grooves 321, the two movable grooves 321 respectively correspond to the first guide 421 and the second guide 422, a part of the first guide 421 is accommodated in one of the movable grooves 321, and the corresponding movable groove 321 is used for guiding the movement direction of the first guide 421, i.e. the first guide 421 can be stably close to or far from the second guide 422; a part of the second guide 422 is received in the other movable groove 321, and the corresponding movable groove 321 serves to guide the moving direction of the second guide 422, i.e., to enable the second guide 422 to be stably moved closer to or farther from the first guide 421. Optionally, the driving assembly 420 includes a motor (not shown), and the first guide 421 and the second guide 422 are in driving connection with the motor, and the distance from the initial position of the first guide 421 to the first end of the channel plate 320 and the distance from the initial position of the second guide 422 to the second end of the channel plate 320 are equal, wherein the first end and the second end are both ends of the channel plate 320 in the width direction of the conveying channel 310; the motor rotates to drive the first guide 421 and the second guide 422 to move synchronously, so that the deviation correcting channel 410 formed between the first guide 421 and the second guide 422 is always located at the center of the conveying channel 310.
The control device 200 of the present embodiment is specifically further configured to: judging whether the width of the sheet medium is smaller than a preset value; in the case that the width of the sheet medium is determined to be smaller than the preset value, determining that the width of the deviation correcting channel 410 needs to be subjected to primary adjustment; in the case where it is determined that the width of the sheet-like medium is not smaller than the preset value, it is determined that the first-order adjustment of the width of the deviation correcting channel 410 is not necessary.
Sheet-like media of smaller width are susceptible to large-angle skew when moving in the conveying path 310; in this embodiment, when the width of the sheet medium is smaller than the preset value, the width of the deviation rectifying channel 410 is adjusted at a first level, so that the sheet medium with a larger angle and smaller width in the conveying channel 310 can be corrected in the process of entering the deviation rectifying channel 410, the sheet medium is prevented from entering the deviation rectifying channel 410 in a larger angle and in a skew state, and further the deviation rectifying mechanism 400 is prevented from being unable to correct the posture of the sheet medium, so that the sheet medium can be ensured to smoothly pass through the deviation rectifying channel 410.
The control device 200 of the present embodiment is further configured to: in the case where it is determined that the width of the sheet-like medium is smaller than the preset value, it is determined that the width of the deviation correcting channel 410 needs to be adjusted secondarily.
When skew occurs in the conveying path 310, the sheet medium having a smaller width has a larger influence on the subsequent processing results of the sheet medium, for example: when the difference between the sheet medium and the two sides of the conveying path 310 is large in the width direction of the conveying path 310, the print content of the printing mechanism 540 may not be printed on the sheet medium. Therefore, in this embodiment, for all sheet mediums with smaller widths, the width of the deviation correcting channel 410 needs to be adjusted secondarily before the sheet mediums are separated from the deviation correcting channel 410, so that the deviation correcting channel 410 is located at the center of the conveying channel 310 by adjusting the width of the deviation correcting channel 410 secondarily, and thus the sheet mediums are centered in the conveying channel 310, that is, the adjusted posture of the sheet mediums with smaller widths can be ensured, so as to improve the processing effect of the following processing mechanism on the sheet mediums.
Specifically, when the sheet medium processing apparatus 010 of the present embodiment processes a sheet medium with a smaller width, before the sheet medium enters the deviation rectifying channel 410, the control device 200 controls the driving assembly 420 to drive the first guide 421 and the second guide 422 to approach each other, that is, to perform a first-stage adjustment on the width of the deviation rectifying channel 410, so that the width of the deviation rectifying channel 410 is adjusted to be the first width, and the sheet medium with a smaller width does not enter the deviation rectifying channel 410 in a skew state with a larger angle; then when the sheet medium moves to the set position of the deviation correcting channel 410, the control device 200 controls the driving assembly 420 to drive the first guide 421 and the second guide 422 to approach each other again, that is, the width of the deviation correcting channel 410 is adjusted in a second level, so that the width of the deviation correcting channel 410 is adjusted to be a second width, that is, the first guide 421 and the second guide 422 clamp the sheet medium in the deviation correcting channel 410 to correct the skew posture of the sheet medium, and the position of the sheet medium is centered in the conveying channel 310, so that the processing result of the sheet medium is improved.
The control device 200 of the present embodiment is further configured to: judging whether the sheet medium is skewed or not under the condition that the width of the sheet medium is not smaller than a preset value; if the sheet medium is judged to be skewed, the second-level adjustment of the width of the deviation correcting channel 410 is judged to be needed; if it is determined that the sheet-like medium is not skewed, it is determined that secondary adjustment of the width of the correction channel 410 is not required.
When the sheet medium with larger width is conveyed in the conveying channel 310, the sheet medium is larger in width, so that large-angle skew cannot occur, the situation that the sheet medium cannot enter the deviation correcting channel 410 due to the large skew angle of the sheet medium cannot occur, and therefore, the first-stage adjustment of the width of the deviation correcting channel 410 can be omitted for the sheet medium with larger width; in addition, in the case of a sheet medium with a large width, when the sheet medium is deflected only in the width direction of the conveying channel 310 in the conveying channel 310, the deflection has a small influence on the subsequent processing result of the sheet medium, even the subsequent processing result is not substantially influenced, so that the sheet medium with a large width can be conveyed normally or deflected only, the secondary adjustment of the width of the deviation correcting channel 410 is not performed, and the deviation correcting channel 410 is only adjusted secondarily when the sheet medium is deflected (i.e. the extending direction of the front edge of the sheet medium is different from the width direction of the conveying channel 310), namely, the driving assembly 420 can be controlled to drive the first guide 421 and the second guide 422 to approach each other so as to clamp the sheet medium, thereby correcting the skew posture of the sheet medium so as to improve the subsequent processing effect.
The control device 200 of the present embodiment is further configured to: after the width of the deviation correcting channel 410 is adjusted in a second level, detecting whether the sheet medium is still in a skew state again; if so, the width of the deviation rectifying channel 410 is adjusted at least once again to rectify the sheet medium at least once again.
Specifically, after the width of the deviation correcting channel 410 is adjusted in two steps, if the control device 200 still detects that the sheet medium in the deviation correcting channel 410 is skewed, the driving assembly 420 may be controlled to drive the first guide 421 and the second guide 422 to move so as to perform posture adjustment on the sheet medium until the skewed posture of the sheet medium is corrected.
Referring to fig. 2, the sheet medium processing apparatus 010 of the present embodiment further includes a position detecting mechanism 510, the position detecting mechanism 510 being located downstream of the deviation rectifying mechanism 400 along the advancing direction of the sheet medium in the conveying path 310, the position detecting mechanism 510 being communicatively connected to the control device 200, the control device 200 being further configured to: when the front end of the sheet medium reaches the detection position of the position detection mechanism 510, judging whether the width of the deviation correcting channel 410 needs to be subjected to secondary adjustment; if so, the conveying mechanism 300 is controlled to drive the sheet medium to retreat by a set distance so as to convey the middle part of the sheet medium into the deviation rectifying channel 410, and then the width of the deviation rectifying channel 410 is subjected to secondary adjustment. Optionally, along the advancing direction of the sheet medium in the conveying channel 310, the distance between the position detecting mechanism 510 and the deviation rectifying channel 410 is smaller than the minimum length of the sheet medium, so that when the front end of the sheet medium reaches the detecting position of the position detecting mechanism 510, the rear end of the sheet medium is not separated from the deviation rectifying channel 410, so that the sheet medium can smoothly retreat in the deviation rectifying channel 410.
Therefore, the position detecting mechanism 510 can be used for detecting the position of the sheet medium in the deviation rectifying channel 410, so as to determine whether the width of the deviation rectifying channel 410 needs to be secondarily adjusted when the sheet medium is not separated from the deviation rectifying channel 410, thereby realizing the secondary adjustment of the width of the deviation rectifying channel 410 when the sheet medium is not separated from the deviation rectifying channel 410, and ensuring that the posture of the sheet medium can be corrected by secondarily adjusting the width of the deviation rectifying channel 410.
When it is determined that the width of the deviation correcting channel 410 needs to be adjusted in the second stage, the conveying mechanism 300 is controlled to drive the sheet medium to retreat by a set distance, so that the middle part of the sheet medium is conveyed into the deviation correcting channel 410, and then the width of the deviation correcting channel 410 is adjusted in the second stage, so that the posture of the sheet medium can be sufficiently corrected when the sheet medium passes through the deviation correcting channel 410 with the width being the second width.

Further, the position detecting mechanism 510 includes a plurality of photosensors arranged in a row along the width direction of the conveyance path 310; when one of the photosensors changes from the non-blocked state to the blocked state, it is determined that the leading end of the sheet medium has moved to the detection position of the position detection mechanism 510.
In other embodiments, the position detecting mechanism 510 may further include an image sensor communicatively coupled to the control device 200, the image sensor being capable of reading an image of the leading end of the sheet-like medium and communicating the image to the control device 200 when the leading end of the sheet-like medium moves to a detection position of the image sensor.

When the control device 200 determines that the width of the sheet medium is smaller than the preset value according to the first signal output by the width detection mechanism 520, it is determined that the width of the deviation rectifying channel 410 needs to be subjected to primary adjustment, and then the width of the deviation rectifying channel 410 needs to be subjected to secondary adjustment; when the control device 200 determines that the width of the sheet-like medium is not smaller than the preset value based on the first signal output from the width detection mechanism 520, it is determined that the first-stage adjustment of the width of the deviation rectifying passage 410 is not necessary.

When the plurality of photosensors of the skew detection mechanism 530 are simultaneously changed from not being blocked to being blocked, it is determined that the sheet-like medium is not skewed; when one of the photosensors in the skew detection mechanism 530 changes from the non-blocking state to the blocked state, the photosensor adjacent to that photosensor changes to the blocked state after a certain interval of time, i.e., it is determined that the sheet-like medium is skewed.
