Fig. 1 is a schematic structural diagram of an active deviation rectifying device 100 according to this embodiment. Referring to fig. 1, the present embodiment provides an active deviation rectifying device 100, which includes a housing 110, a paper feeding sensor 123, an abnormal sensor 124, a deviation rectifying member 130, and an in-position sensor. The casing 110 has a running path 111 for the paper to be corrected to run, and the paper feeding sensor 123 and the abnormality sensor 124 are disposed at both sides of the running path 111 at intervals, so that whether the paper feeding is correct is determined by whether the paper feeding sensor 123 and the abnormality sensor 124 are blocked. The deviation correcting member 130 is arranged in the running channel 111, and the paper feeding sensor 123 and the abnormal sensor 124 are both electrically connected with the deviation correcting member 130, so that the deviation correcting member 130 is controlled to correct the deviation according to the detection results of the paper feeding sensor 123 and the abnormal sensor 124, and the deviation correcting member 130 drives the carton to be corrected to move in the direction close to the paper feeding sensor 123. The active deviation correcting device 100 obtains the paper feeding position by arranging the paper feeding sensor 123 and the abnormal sensor 124, when the paper feeding is correct, the deviation correcting part 130 is controlled to actively correct the deviation, the deviation correcting effect is good, and meanwhile, the active deviation correcting device 100 can meet the requirement of correcting deviation of paper to be corrected with various specifications. In this embodiment, the "paper to be corrected" is strip paper such as paper money or bills.
The following further describes the active deviation rectifying device 100 provided in this embodiment:
referring to fig. 1, in the embodiment, one side of the casing 110 has an inlet 112, a direction from the inlet 112 to the running channel 111 is an extending direction of the running channel 111, and when in use, the paper to be corrected enters the running channel 111 of the casing 110 from the inlet 112 and travels toward the casing 110 along the extending direction of the running channel 111.
The active deviation correcting device 100 further includes a controller (not shown), and the paper feeding sensor 123, the abnormal sensor 124, the in-position sensor and the deviation correcting member 130 are electrically connected to the controller, so that the paper feeding sensor 123, the abnormal sensor 124, the in-position sensor and the deviation correcting member 130 are electrically connected. It is understood that in other embodiments, a control element such as a PLC may be built in the deviation rectifying member 130.
The paper feeding sensor 123, the abnormal sensor 124 and the in-place sensor are all used for detecting the position of the paper to be corrected, specifically, when the paper to be corrected moves to the paper feeding sensor 123, the abnormal sensor 124 or the in-place sensor, the sensor at the corresponding position is shielded, so that the sensor outputs a signal representing shielding to the controller; when the paper to be corrected does not move to the paper feeding sensor 123, the abnormal sensor 124 or the in-place sensor, the sensor at the corresponding position is not shielded, so that the sensor outputs a signal representing the non-shielding to the controller. The controller controls the deviation rectifying member 130 according to the received signal. Alternatively, the paper feed sensor 123, the abnormality sensor 124, and the in-position sensor are all infrared sensors.
It should be noted that, in the description of the present embodiment, the "outputting a signal indicating that the sensor is not shielded" should be understood in a broad sense, and may be an electrical signal containing information that the sensor is not shielded, or may be an electrical signal that is not output, and the controller may be capable of determining whether the sensor is shielded according to the state of the sensor.
In this embodiment, the paper feeding sensor 123 and the abnormality sensor 124 are disposed at two sides of the operation channel 111 at an interval, and the paper feeding sensor 123 and the abnormality sensor 124 are disposed at one end of the operation channel 111 close to the inlet 112, so that the paper to be corrected can be detected by the paper feeding sensor 123 and the abnormality sensor 124 after entering the operation channel 111. When the paper feeding sensor 123 is not shielded and the abnormality sensor 124 is shielded, it indicates that the paper feeding is abnormal, and the controller outputs a control signal to report that the paper feeding is abnormal and wrong. When the paper feeding sensor 123 is shielded and the abnormal sensor 124 is not shielded, which indicates that the paper feeding is normal, the controller controls the deviation rectifying member 130 to start to rectify the deviation.
Further, a floating roller 121 is disposed at the inlet 112, and when the paper to be corrected enters the housing 110 from the inlet 112 under the operation of the user, the floating roller 121 applies a certain clamping force to the paper to be corrected, so as to position the paper to be corrected.
After the deviation correction is carried out for a period of time, the deviation correction result can be judged through signals output by the in-place sensor and the paper feeding sensor 123. Optionally, the in-place sensors include a pre-deviation-correction sensor 125 and a post-deviation-correction sensor 126, and the paper feeding sensor 123, the pre-deviation-correction sensor 125, and the post-deviation-correction sensor 126 are sequentially arranged along the extending direction of the running channel 111, that is, during the process from the deviation correction to the movement along the running channel 111, the paper feeding sensor 123, the pre-deviation-correction sensor 125, and the post-deviation-correction sensor 126 are sequentially passed through. When the sensor 125 before the deviation correction and the sensor 126 after the deviation correction are both blocked, indicating that the in-place sensor is blocked; when neither the pre-deskew sensor 125 nor the post-deskew sensor 126 is occluded, it indicates that the in-position sensor is not occluded.
The deviation correcting member 130 is disposed in the running passage 111, that is, along the width direction of the running passage 111, the paper feed sensor 123 and the abnormality sensor 124 are located at the edge of the running passage 111, the deviation correcting member 130 is disposed near the middle of the running passage 111 with respect to the paper feed sensor 123 and the abnormality sensor 124, and the deviation correcting member 130 is located far from the inlet 112 with respect to the paper feed sensor 123 and the abnormality sensor 124. It should be noted that, in the description of the present embodiment, the "width direction of the travel passage 111" is a direction perpendicular to the extending direction of the travel passage 111.
Optionally, the rectification member 130 includes a rectification pressure plate 131, a rectification motor 132, and a rectification wheel 133. The deviation-rectifying pressing plate 131 is movably connected with the casing 110, and the deviation-rectifying motor 132 is fixedly connected to the deviation-rectifying pressing plate 131 so as to move up and down under the driving of the deviation-rectifying pressing plate 131. The deviation rectifying wheel 133 is connected to the deviation rectifying motor 132 in a transmission manner, so that the deviation rectifying motor 132 drives the paper to be rectified to move in a direction close to the paper feeding sensor 123, and further the deviation rectification is performed. Meanwhile, when the deviation rectifying motor 132 moves up and down under the driving of the deviation rectifying pressing plate 131, the deviation rectifying wheel 133 moves up and down synchronously with the deviation rectifying motor 132, so that the paper to be corrected is pressed or loosened by the deviation rectifying wheel 133.
Referring to fig. 1 again, in the embodiment, the active deviation rectifying device 100 further includes a driving roller 122 disposed on a side of the deviation rectifying member 130 away from the inlet 112, and the driving roller 122 is configured to drive the paper to be corrected after the deviation rectification is completed to move in a direction away from the inlet 112. Specifically, the driving roller 122 is disposed at the end of the running channel 111, and after the deviation correction is completed, the paper to be corrected runs to the driving roller 122 and is driven by the driving roller 122 to be conveyed backwards, so as to perform the next step.
Further, the active deviation rectification device 100 further includes a driving member 141 and a ready sensor 127 in communication with the driving member 141. The driving member 141 is connected to the driving roller 122 for driving the driving roller 122 to rotate. The ready sensors 127 are arranged side by side on the side of the in-position sensor far away from the paper feeding sensor 123, and are used for detecting whether the paper to be corrected reaches the ready sensors 127. Specifically, the ready sensor 127 is disposed at the front side of the driving roller 122, and the paper feeding sensor 123, the pre-correction sensor 125, the post-correction sensor 126, and the ready sensor 127 are sequentially disposed along the running path 111. Both the ready sensor 127 and the driver 141 are electrically connected to the controller, thus electrically connecting the ready sensor 127 and the driver 141. When the paper to be corrected runs to the ready sensor 127 and the ready sensor 127 is shielded, the ready sensor 127 outputs a signal representing shielding to the controller, and the controller controls the driving member 141 to start according to the signal, so as to drive the driving roller 122 to work, and convey the paper to be corrected to the next device.
Optionally, the active deviation rectifying device 100 further includes a transmission belt 142, and the transmission belt 142 is in transmission connection with the driving member 141 and the transmission roller 122 at the same time, so as to realize power transmission between the driving member 141 and the transmission roller 122.
The active deviation rectifying device 100 provided by this embodiment has at least the following advantages:
the active deviation correcting device 100 provided by this embodiment detects the positions of the paper to be corrected before and after deviation correction by arranging the paper feeding sensor 123, the abnormal sensor 124, the in-place sensor and the ready sensor 127, and actively corrects the deviation of the paper to be corrected according to the detection result, so that the deviation correcting effect is good, and meanwhile, the active deviation correcting device 100 can meet the requirement of performing deviation correcting processing on paper to be corrected of various specifications.
Fig. 2 is a step diagram of the deviation rectifying control method provided in this embodiment. Referring to fig. 1 and fig. 2, the present embodiment also provides a deviation rectification control method for controlling the active deviation rectification device 100. In this embodiment, the deviation rectification control method includes:
s01: the states of the paper feed sensor 123 and the abnormality sensor 124 are acquired.
And the state detection thread updates and detects the states of the sensors in sequence every 10 ms. Alternatively, the paper feed sensor 123 outputs a first signal indicating an occlusion state, and the abnormality sensor 124 outputs a second signal indicating an occlusion state. Specifically, when the paper to be corrected moves to the upper side of the paper feeding sensor 123 and shields the paper feeding sensor 123, the first signal representation output by the paper feeding sensor 123 is shielded, and correspondingly, if the paper to be corrected does not shield the paper feeding sensor 123, the first signal representation output by the paper feeding sensor 123 is not shielded. Similarly, when the paper to be corrected runs to the upper side of the abnormal sensor 124 and shields the abnormal sensor 124, the first signal output by the abnormal sensor 124 represents shielding, and correspondingly, if the paper to be corrected does not shield the abnormal sensor 124, the first signal output by the abnormal sensor 124 represents non-shielding.
S02: and judging whether the paper feeding is normal or not.
If the first signal represents the occlusion and the second signal represents the non-occlusion, it indicates that at least a part of the paper to be corrected is located on the upper side of the paper feeding sensor 123 and the abnormal sensor 124 is not occluded, which indicates that the paper feeding is normal. If the first signal representation is not shielded and the second signal representation is shielded, it indicates that the paper to be corrected is not positioned at the upper side of the paper feeding sensor 123, and indicates that the paper feeding is abnormal, and at this time, the paper feeding is reported to be abnormal and wrong.
S03: the deviation correcting member 130 is controlled to correct the deviation so as to drive the paper to be corrected to move towards the direction close to the paper feeding sensor 123.
And controlling the deviation correcting member 130 to correct the deviation under the condition that the paper feeding is normal.
The correction process specifically comprises the following steps: controlling the operation of the deviation rectifying member 130. The deviation rectifying pressure plate 131 is controlled to press down, so that the deviation rectifying motor 132 and the deviation rectifying wheel 133 are driven to synchronously press down, and the paper to be subjected to deviation rectification is pressed on the lower side of the deviation rectifying wheel 133. After the paper is pressed, the correction is started after 10ms, that is, the correction motor 132 is started, the correction motor 132 drives the correction wheel 133 to rotate forward, and the paper to be corrected moves along the running channel 111 under the drive of the correction wheel 133 and deflects to the side close to the paper feeding sensor 123.
S04: and acquiring a third signal of the representation shielding state output by the in-place sensor to judge whether the deviation correction is successful.
Specifically, after the deviation correction motor 132 is started, the acquisition of the first signal and the third signal is started after 100ms, and the acquisition of the first signal and the third signal is started every 20 ms.
a1, if the first signal mark obtained is shielded within the preset time length and the third signal is characterized by shielding, the rectification is judged to be successful.
The in-place sensors include a pre-deviation sensor 125 and a post-deviation sensor 126, and the paper feeding sensor 123, the pre-deviation sensor 125 and the post-deviation sensor 126 are sequentially distributed along the extending direction of the running channel 111. When the pre-deviation-correction sensor 125 and the post-deviation-correction sensor 126 are both blocked, the pre-deviation-correction sensor 125 and the post-deviation-correction sensor 126 both output signals representing blocking, and then represent a third signal output by the in-place sensor representing blocking. When both the pre-deviation sensor 125 and the post-deviation sensor 126 are not shielded, both the pre-deviation sensor 125 and the post-deviation sensor 126 output signals representing non-shielding, and the third signal representing the output of the in-place sensor represents non-shielding.
Optionally, the preset time duration is 500ms, when step S04 is started, multiple sets of first signals and third signals are obtained within 500ms, and when the first signal and the third signal in a certain set of the first signals and the third signals both represent occlusion, that is, if there is paper in the paper feeding sensor 123, the pre-correction sensor 125, and the post-correction sensor 126, the correction is considered to be successful.
a 2: if the first signal and the third signal obtained within the preset time length both represent that the signal is not shielded, the deviation correcting part 130 is controlled to be closed, and meanwhile, a deviation correcting failure is reported.
Sets of the first signal and the third signal obtained within 500ms after the execution of step S04 is started. When the first signal and the third signal in a certain group of the first signal and the third signal are both represented to be not shielded, that is, no paper exists at the paper feeding sensor 123, the pre-correction sensor 125 and the post-correction sensor 126, the correction is considered to be failed, and at this time, a correction failure error is reported, and the correction motor 132 is controlled to be turned off.
a 3: if the situation that the acquired first signal and the acquired third signal simultaneously represent the shielding state does not occur within the preset time length, the deviation rectification is judged to be overtime, and meanwhile, the deviation rectification piece 130 is controlled to rectify the deviation again.
After the execution of step S04 is started, if the a1 and a2 do not occur within 500ms, it is determined that the skew correction is overtime. At this time, the deviation correcting member 130 is controlled to correct the deviation again.
a 4: if the correction overtime times are larger than the preset times, a correction failure is reported, and the correction piece 130 is controlled to rotate reversely.
In the case of a3, the deviation correcting member 130 corrects the deviation again, if the deviation correction is still overtime, the deviation correction is performed again, and if the deviation correction is still overtime again after the deviation correction is performed for three times again, the deviation correction failure is reported, and the deviation correcting motor 132 is controlled to rotate reversely, so that the paper is returned.
S05: a fourth signal indicative of an occlusion state output by the ready sensor 127 is acquired.
