Referring to fig. 2 and 3, the deviation correcting mechanism 400 of the present embodiment includes a driving assembly 420, and a first guiding member 421 and a second guiding member 422 movably disposed in the conveying passage 310, wherein the first guiding member 421 and the second guiding member 422 are disposed at intervals along the width direction of the conveying passage 310, and a deviation correcting passage 410 is formed between the first guiding member 421 and the second guiding member 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, and the driving assembly 420 is used for driving the first guide 421 and the second guide 422 to move closer to or away from each other to adjust the width of the deviation rectifying channel 410, that is, the driving assembly 420 is 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 can be selected according to the requirement, and the driving assembly 420 of this embodiment includes two rack and pinion transmission assemblies, and the two rack and pinion transmission assemblies are respectively in transmission connection with the first guide piece 421 and the second guide piece 422; in other embodiments, the drive assembly 420 may also include a conveyor belt assembly, a lead screw drive assembly, or the like.
Each of the first guide 421 and the second guide 422 may be a guide bar, a guide plate, or the like, and is 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 correspond to the first guide piece 421 and the second guide piece 422 respectively, a part of the first guide piece 421 is accommodated in one of the movable grooves 321, and the corresponding movable groove 321 is used for guiding the moving direction of the first guide piece 421, i.e. the first guide piece 421 can be stably close to or far away from the second guide piece 422; a portion of the second guide 422 is received in the other movable groove 321, and the corresponding movable groove 321 serves to guide a moving direction of the second guide 422, i.e., to allow the second guide 422 to be stably close to or far from the first guide 421. Optionally, the driving assembly 420 includes a motor (not shown in the figure), the first guiding member 421 and the second guiding member 422 are in transmission connection with the motor, and the distance from the initial position of the first guiding member 421 to the first end of the channel plate 320 is equal to the distance from the initial position of the second guiding member 422 to the second end of the channel plate 320, where the first end and the second end are two 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 rectifying 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 further specifically configured to: judging whether the width of the sheet medium is smaller than a preset value or not; under the condition that the width of the sheet medium is smaller than the preset value, the requirement for primary adjustment on the width of the deviation rectifying channel 410 is judged; in the case where it is determined that the width of the sheet-like medium is not less than the preset value, it is determined that the primary adjustment of the width of the correction passage 410 is not necessary.
The sheet-like medium with a smaller width is prone to be skewed at a larger angle when moving in the conveying channel 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 one level, so that the sheet medium with a large angle and a small width in the conveying channel 310 can be corrected in the process of entering the deviation rectifying channel 410, and the sheet medium is prevented from entering the deviation rectifying channel 410 in a large angle, thereby preventing the deviation rectifying mechanism 400 from being unable to correct the posture of the sheet medium, and ensuring that the sheet medium can smoothly pass through the deviation rectifying channel 410.
The control device 200 of the present embodiment is further configured to: under the condition that the width of the sheet-like medium is judged to be smaller than the preset value, the width of the deviation rectifying channel 410 is judged to need to be adjusted in a secondary mode.
When the sheet-like medium with a small width is skewed in the conveying path 310, the subsequent processing results of the sheet-like medium may be greatly affected, for example: if the difference in the distance between the sheet-like medium and the both sides of the conveyance path 310 in the width direction of the conveyance path 310 is large, the print content of the printing mechanism 540 may not be printed on the sheet-like medium. Therefore, in this embodiment, before all the sheet mediums with smaller widths are separated from the deviation rectifying channel 410, the width of the deviation rectifying channel 410 needs to be adjusted in two stages, so that the deviation rectifying channel 410 is located at the center of the conveying channel 310 by adjusting the width of the deviation rectifying channel 410 in two stages, and the sheet mediums with smaller widths are centered in the conveying channel 310, that is, the posture of the sheet mediums with smaller widths can be adjusted, so as to improve the processing effect of the subsequent processing mechanism on the sheet mediums.
Specifically, when the sheet medium processing apparatus 010 of this embodiment processes a sheet medium with a smaller width, before the sheet medium enters the deviation rectifying channel 410, the control device 200 is first used to control the driving assembly 420 to drive the first guiding member 421 and the second guiding member 422 to approach each other, that is, the width of the deviation rectifying channel 410 is first adjusted, 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 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 again, that is, the width of the deviation rectifying channel 410 is adjusted in a secondary manner, so that the width of the deviation rectifying channel 410 is adjusted to be the second width, that is, the first guide 421 and the second guide 422 clamp the sheet medium in the deviation rectifying 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, thereby improving the subsequent processing result of the sheet medium.
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 judged to be not smaller than a preset value; if the sheet type medium is judged to be skewed, the width of the deviation rectifying channel 410 is judged to need to be adjusted in a second level; if it is determined that the sheet-like media is not skewed, it is determined that secondary adjustment of the width of the deskew channel 410 is not required.
For the sheet medium with a larger width, when the sheet medium is conveyed in the conveying channel 310, the sheet medium is larger in width, so that the sheet medium cannot be skewed at a larger angle, and the situation that the sheet medium cannot enter the deviation rectifying channel 410 due to the larger skew angle of the sheet medium cannot occur, so that the sheet medium with a larger width can not be subjected to primary adjustment of the width of the deviation rectifying channel 410; in the case where the sheet-like medium having a large width is deflected only in the width direction of the conveyance path 310 in the conveyance path 310, the skew has little or no influence on the subsequent processing result of the sheet-like medium, and therefore, for the sheet-like medium with larger width, the secondary adjustment of the width of the deviation rectifying channel 410 may not be performed when the sheet-like medium is normally conveyed or only deflects, and the secondary adjustment of the deviation rectifying channel 410 is performed only when the sheet-like medium deflects (i.e., the extending direction of the front edge of the sheet-like medium is different from the width direction of the conveying channel 310), that is, the first guide 421 and the second guide 422 can be driven to approach each other by controlling the driving assembly 420, so as to clamp the sheet-like medium, therefore, the skew posture of the sheet medium is corrected, so that the subsequent processing effect is improved.
The control device 200 of the present embodiment is further configured to: after the width of the deviation rectifying channel 410 is adjusted in a second level, whether the sheet medium is still in a skew state is detected again; if yes, the width of the deviation rectifying channel 410 is adjusted at least once again, so that the sheet-like medium is rectified at least once again.
Specifically, after the secondary adjustment of the width of the deviation correcting channel 410, if the control device 200 still detects that the sheet-like 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 to perform posture adjustment on the sheet-like medium until the skewed posture of the sheet-like medium is corrected.
Referring to fig. 2, the sheet media processing apparatus 010 of the embodiment further includes a position detecting mechanism 510, the position detecting mechanism 510 is located downstream of the deviation rectifying mechanism 400 along the advancing direction of the sheet media in the conveying path 310, the position detecting mechanism 510 is communicatively connected to the control device 200, and the control device 200 is 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 rectifying channel 410 needs to be adjusted for the second level; if so, the conveying mechanism 300 is controlled to drive the sheet-like medium to retreat for a set distance so as to convey the middle part of the sheet-like medium into the deviation rectifying channel 410, and then the width of the deviation rectifying channel 410 is adjusted in a secondary mode. Optionally, in the advancing direction of the sheet-like 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-like medium, so that when the front end of the sheet-like medium reaches the detection position of the position detecting mechanism 510, the rear end of the sheet-like medium does not yet separate from the deviation rectifying channel 410, and the sheet-like medium can smoothly retreat in the deviation rectifying channel 410.
