Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the embodiment, the operator is used as a reference, and the direction close to the operator is a proximal end, and the direction away from the operator is a distal end.

The stall adjustment method of the deflection wheel/ball sorting system of the present invention will be explained with reference to the accompanying drawings, the method is used in a deflection wheel/ball sorting system, as shown in fig. 1, comprising a conveyor line 100, a deflection wheel/ball conveyor 200 and a sorting mouth 300, said conveyor line 100 and deflection wheel/ball conveyor 200 being staggered, namely in the manner of the conveying line 100-the deflecting wheel/ball conveyor 200-the conveying line 100 … …, the sorting openings 300 are located on one or both sides of the deflection wheel/ball conveyor 200, and preferably has an opening width greater than the width of the deflection wheel/ball conveyor 200 (the distance from the input end to the output end of the deflection wheel/ball conveyor).

The conveyor line 100 may be any of various known conveying devices, such as a belt conveyor, a roller conveyor, etc., preferably a belt conveyor. The deflecting wheel/ball conveyor 200 may be any known deflecting conveyor apparatus such as those disclosed in application nos. 201711324633.8, 201910265828.2, etc.

As shown in fig. 1, sensors Y1, Y2, … … and Yn are disposed on each conveying line 100 near the sorting opening 300, and the sensors Y1, Y2, … … and Yn may be various photoelectric sensors for determining whether packages are moved to their corresponding mounting positions, so as to perform corresponding control or adjustment.

During normal sorting, after the route of the package is determined, when the package moves to the corresponding sorting cell 300, the wheels or balls of the deflection wheels/balls 200 at the corresponding positions are turned to enable the package to enter the corresponding sorting cell to be sorted.

The specific working process is shown in the attached figure 3:

and S10, starting the system, and enabling the conveying lines, the deflection wheel/ball sorting machine, the control device and the like to normally operate.

S20, as shown in fig. 2, the package is placed on the upper envelope 600 and transported to the first transport line 100 manually or by an automated device, and the package routing information is obtained at the first transport line 100 by a code scanning device, wherein the code scanning device 500 may be disposed in front of the tracking trigger photo 400 of the first transport line 100 (where the front is the position that the package passes through first during the transport process).

Further, the yard device 500 can also be swept by six faces located in front of the first conveying line 100, so that the difficulty of loading the package can be reduced by the known six faces, for example, a yard device 500 is respectively arranged at the front, back, left, right, upper and lower sides of an upper envelope line 600 arranged in front of the first conveying line 100, and a lens of the yard device at the bottom is located at a gap between the upper envelope line 600 and the first conveying line 100, and a transparent support plate, such as transparent glass, is arranged at the gap and is flush with the conveying surfaces of the upper envelope line 600 and the conveying line 100, of course, the specific structure of the six faces yard device can also be known other technologies, and the description is omitted here.

When the route is acquired, the package can be directly placed on the first conveying line in front of the tracking trigger photoelectric unit 400 after being scanned by manual or automatic equipment.

When the package route is acquired, whether the route is accurately acquired needs to be determined, if the route information is not effectively acquired, the first delivery line 100 of the package is moved out manually or through automatic equipment, and corresponding data is cleared; of course in other embodiments it is also possible to have the conveyor lines and deflecting wheels/balls convey packages forward without sorting.

And S30, the packages move along with the first conveying line 100 and pass through the tracking trigger photoelectricity 400, tracking is started to determine whether the packages move to the position of the target grid, specifically, the number of pulses of an encoder of a driving motor of the conveying line is calculated, so that the moving time of the packages is determined according to the number of pulses, and the positions of the packages on the conveying line can be determined according to the conveying speed of the conveying line.

During the delivery of the package from the first conveyor line to the destination cell,

counting the actual pulse count of the parcel from the set position (tracking trigger photoelectric installation position) of the first conveying line to each sensor Y1, Y2, … … and Yn, comparing each actual pulse count N1, N2, … … and Nn with the standard pulse count N1, N2, … … and Nn of the corresponding distance, modifying the actual pulse count N1, N2, … … and Nn into the corresponding standard pulse count when a certain actual pulse count N1, N2, … … and Nn is not matched with the standard pulse count N1, N2, … … and Nn, and continuously counting the actual pulse count from the sensor to the next sensor on the basis of the modified data. In this embodiment, the rotational speed of the drive motor of each conveyor line 100 corresponds to the rotational speed of the drive motor of the deflection ball/wheel 200, i.e. the pulse frequency of the motors, and since the length of the deflection wheel/ball 200 is known, the number of pulses required to wrap on it can be directly calculated, so that the standard pulse count for moving from the set position X to each sensor Y1, Y2, … …, Yn and the pulse count required from the set position X to each sorting cell can be known.

As will be described below with reference to specific examples, for example, the target cell of a parcel is the first sorting cell, since the distance between the tracking trigger photo 400 and the sensor Y1 and the distance between the parcel under the target cell are known, the standard pulse count of the movement from the tracking trigger photo to the sensor and the target cell can be calculated, for example, 80 and 100, respectively, at this time, only the actual pulse count N1 of the movement of the parcel from the tracking trigger photo 400 to the sensor Y1 on the first conveyor line needs to be counted, the actual pulse count N1 is compared with the standard pulse count N1, and when the actual pulse count N1 is consistent with the standard pulse count N1, namely 80, the sorting can be performed by continuing the counting pulse count based on the actual pulse count 80 until the actual pulse count reaches 100, that is 100.

However, during the transportation process of the parcel in the conveying line, due to the fact that the parcel stalls due to slipping, collision, external force interference and the like, when the parcel moves to the sensor Y1 from the tracking touch photoelectric sensor 400, the parcel moves effectively at a certain position, but the actual pulse count is still increased, which causes the actual pulse count when the parcel moves to the sensor Y1 to be larger than 80, for example, 90 is reached, at this time, if the pulse count is counted continuously on the basis of 90, the sorting can be performed as long as 10 pulses are counted again, and 100 pulses are reached, but the standard pulse count before the sensor Y1 and the target grid should be 20 (100-80), which causes the parcel to exist and not move to the target parcel position if the sorting is performed according to the actual pulse count, and greatly affects the sorting accuracy.

Therefore, in practical application, when the parcel moves to the sensor Y1, whether the current actual pulse count N1 is inconsistent with the standard pulse count N1 is confirmed, if the actual pulse count N1 is inconsistent with the standard pulse count N1, namely 90 is adjusted to 80, the pulse count is continuously counted on the basis of 80, and the number of pulses can be counted for 100 times after 20 times of pulses are counted again, so that the accuracy of the parcel position is ensured.

In more cases, however, the package may need to pass through multiple sorting bays to reach the target bay, and the difficulty of controlling the same may increase.

For example, the target cell of the parcel is at the fourth cell, and the parcel starts to track the parcel position after the parcel passes through the tracking trigger photoelectric unit 400, namely counting pulse,

when the packages pass through the sensor Y1 on the first conveyor line, the adjustment is performed in the adjustment mode at the sensor Y1 according to the above embodiment, that is, after the pulse count when the packages are fed to the sensor Y1 is adjusted to 80, the pulse counts of the packages from the sensor Y1 on the first conveyor line to the sensor Y2 on the second conveyor line are accumulated on the basis of 80, so that the actual pulse count N2 required by the packages from the tracking trigger photoelectric sensor 400 to the sensor Y2 is obtained.

And comparing the actual pulse count N2 with the standard pulse count N2 of the package from the tracking trigger photoelectric sensor 400 to the sensor Y2, and counting the actual pulse count from the sensor Y2 to the sensor Y3 on the third conveying line on the basis of the target pulse count N2 to obtain the actual pulse count N3 required by the package from the tracking trigger photoelectric sensor 400 to the sensor Y3 if the actual pulse count N2 is greater than the target pulse count N2.

And comparing the actual pulse count N3 with the standard pulse count N3 of the package from the tracking trigger photoelectric sensor 400 to the sensor Y3, and if the actual pulse count N3 is greater than the target pulse count N3, continuously counting the actual pulse count of the package from the sensor Y3 to the sensor Y4 on the fourth conveying line on the basis of the target pulse count N3 so as to obtain the actual pulse count N4 required by the package from the tracking trigger photoelectric sensor 400 to the sensor Y4.

Comparing the actual pulse count N4 with the standard pulse count N4 of the parcel from the tracking trigger photoelectric sensor 400 to the sensor Y4, and if the actual pulse count N4 is greater than the target pulse count N4, continuing to accumulate the remaining actual pulse count N from the sensor Y4 to the target grid on the basis of the target pulse count N4_{The residue is left}And the target lattice can be reached and the sorting can be carried out.

In addition, because packages are continuously supplied to the sortation system, and packages are continuously entering, there are often multiple packages on the main conveyor line, which increases the difficulty of accurately tracking each package. Therefore, in order to effectively track the packages, when the packages are tracked and the packages pass through the first tracking trigger photoelectric device, a data window is created for the packages, tracking data of the packages are written into the data window, and the data window is deleted after the packages are sorted. Therefore, the data windows between the packages are independent, no influence exists between the packages, and even if one data window is abnormal, the other data windows are not abnormal.

Further, in order to reduce pulse counting errors caused by the fact that packages are stalled after passing through the sensors Y1, Y2, … … and Yn, the installation positions of the sensors Y1, Y2, … … and Yn meet the condition that the standard pulse counting of the sensors Y1, Y2, Yn to the set position X is between 80% and 92% of the standard pulse counting of the sensors Y1, Y2, Yn to each target grid; i.e., if the pulse count of the package from the tracking trigger photo to the target bin is 100, then the pulse count of the package to the tracking trigger photo sensor Y1 is between 80-92.

In a more preferred embodiment, to achieve further automation and reduce manual operations, the upper envelope wire 100 may also be fed by various single piece separating devices 700, as shown in fig. 2.

The single-piece separating apparatus may be any of various known single-piece separating apparatus, such as those disclosed in the prior art patent applications 201811248299.7, 201821996015.8, and the like, or may be of the preferred construction hereinafter.

As shown in fig. 4, the single-piece separating device includes an upper covered wire 1, and the upper covered wire 1 may be various known belt conveyors, roller conveyors, etc., which are known in the art and are not described in detail herein.

As shown in fig. 4, the output end of the edge-abutting machine 2 is connected to the input end of the edge-abutting machine 2, the edge-abutting machine 2 may be various known roller edge-abutting devices, the specific structure of the edge-abutting machine is the prior art, and details are not described, and the length and width of the edge-abutting machine meet the requirement that a package on one side can move to the side to which the package is to abut when the package is input from the input end.

In order to avoid the conveying resistance caused by collision and friction between the package and the side portion of the edge-abutting machine 2 when the package moves to the side to which the edge-abutting machine 2 is to be abutted, as shown in fig. 5, a set of buffer rollers 21 having axes perpendicular to the conveying surface of the package are provided on the edge-abutting machine 2 on the side to which the package is to be abutted, the buffer rollers 21 extend from the vicinity of the input end of the edge-abutting machine 2 to the output end, the buffer rollers 21 may be silica gel wheels, rubber wheels or the like, and may rotate, for example, each buffer roller 21 is fixed to a column 22 on the side to which the edge-abutting machine 2 is to be abutted by a bearing or the like. Simultaneously every the periphery of buffer roller 21 extends to in the conveying face of nearing limit machine 2 to when the parcel is carried to nearing one side to the nearing limit machine with buffer roller 21 contact, and buffer roller 21 can slow down the impact of product through its softer texture, in addition, buffer roller 21 is promoted the rotation by the parcel, thereby reduces frictional force, guarantees the smooth and easy nature of carrying.

As shown in fig. 4, the output end of the edge alongside machine 2 is connected with a first conveying line 3 and a reverse edge alongside machine 4 which are sequentially arranged from one side to the other side, and the output end of the first conveying line 3 is connected with the input end of a second conveying line 5.

And the width of the output end of the edge alongside machine 2 is not less than the sum of the widths of the first conveying line 3 and the reverse edge alongside machine 4. In a preferred embodiment, the width of the output end of the edge-alongside machine 2 is greater than the sum of the widths of the first conveyor line 3 and the reverse edge-alongside machine 4, so that the part of the edge-alongside machine 2 located outside the reverse edge-alongside machine 4 can be directly moved out to the outside, thereby reducing the number of parcels falling onto the reverse edge-alongside machine 4.

The first conveying line 3 can be of various possible structures, and in a possible embodiment, as shown in fig. 4, the first conveying line 3 includes a plurality of parallel narrow belt conveying lines 31 with the same conveying surface height, the two ends of the plurality of narrow belt conveying lines 31 are flush, and each narrow belt conveying line 31 is provided with a separate power source and connected with a control device (not shown in the figure) and is controlled by the control device to operate. Here, the specific structure of the narrow belt conveyor 31 is similar to that of a conventional belt conveyor, and is known in the art and will not be described in detail here. Meanwhile, in the preferred embodiment, the roller of each narrow belt conveyor 31 is driven by a built-in motor, but the roller of each narrow belt conveyor 31 can also be driven by a respective motor in combination with a transmission structure.

When the conveying device is applied specifically, when the overlapped packages are arranged on the first conveying line, the conveying speed of different narrow-band conveying lines can be adjusted, so that the overlapped packages are completely staggered.

In addition, because the size of the packages is not determined, in order to avoid that different narrow strip conveying lines may affect the conveying of other packages when subsequently operating at different speeds, a row of support rollers 32 is arranged between adjacent narrow strip conveying lines 31, as shown in fig. 6.

In another possible embodiment, as shown in fig. 7, the first conveyor line 3 comprises a plurality of parallel narrow belt conveyor lines 31 of the above-described embodiment and a deflecting wheel/ball sorter 33 between the narrow belt conveyor lines 31 and the reverse edge trimmer 4, the conveying surfaces of the narrow belt conveyor lines 31 and the deflecting wheel/ball sorter 33 being flush. In order not to change the width of the conveying surface of the original first conveying line 3, space can be provided for the deflecting wheel/ball sorter 33 by reducing the number of the narrow strip conveying lines 31 in the above-described embodiment.

Of course, in the embodiment where the first conveyor line 3 has the deflecting wheel/ball sorting machine 33, the plurality of narrow belt conveyor lines 31 may also be various conveyor devices, such as a belt conveyor, a roller conveyor, a deflecting wheel/ball sorting machine, and the like, for conveying the packages along the edge of the edge-abutting machine 2 to the rear, and a baffle (not shown in the figure) is disposed on the side of the first conveyor line 3, which is to be adjacent to the edge-abutting machine 2.

The deflecting wheel/ball sorter may be any known deflecting conveyor apparatus, such as those disclosed in the application nos. 201721728210.8, 201910265828.2, etc., configured to a set length and width.

The normal conveying speed and conveying direction of the deflecting wheel/ball sorting machine are the same as the conveying direction of the narrow belt conveying lines 31, namely the deflecting wheel/ball sorting machine conveys the narrow belt conveying lines in the direction of the second conveying line 5; in another state, the conveying direction of the deflecting wheel/ball sorter 33 can be switched to the side of the narrow strip conveying line 31 or the side of the reverse edger 4.

Further, as shown in fig. 8, at least one row of supporting balls or wheels 34 with the top equal to the conveying surface of the narrow belt conveying line 31 and the deflecting wheel/ball sorting machine 33 are also arranged, and the supporting balls or wheels 34 can be various known directional balls or universal balls. When it is a directional wheel or a ball, the axis of the supporting shaft is perpendicular to the conveying direction of the narrow belt conveying line 31. Thus, when conveying, especially when two parallel parcels are arranged on the first conveying line 3, the two parallel parcels can be staggered by adjusting the conveying speed of the narrow belt conveying line 31 and the deflection wheel/ball sorting machine, and meanwhile, the arrangement of the supporting balls or the wheels 34 can reduce the conveying influence on the parcels before and after the parallel parcels when the speeds of the two sides are different.

The edge-approaching direction of the reverse edge-approaching machine 4 is opposite to the edge-approaching direction of the edge-approaching machine 2, the specific structure of the reverse edge-approaching machine is similar to that of the edge-approaching machine 4, and the difference is that the inclination directions of the rotating rollers of the reverse edge-approaching machine 4 are opposite to that of the rotating rollers of the reverse edge-approaching machine, so that the edge-approaching in the opposite direction is realized.

The second conveyor line 5 may be any known conveying equipment, such as a belt conveyor, a roller conveyor, a deflecting wheel/ball sorter, etc., and preferably, it is a belt conveyor and has a length greater than that of the first conveyor line 3.

In addition, in order to pull the distance between the front and rear parcels, the conveying speed of the second conveying line 5 is higher than the conveying speeds of the narrow belt conveying line 31 and the deflecting wheel/ball sorting machine 33, and meanwhile, the second conveying line 5 comprises at least two sections, and the conveying speed of each section is lower than that of the rear section thereof, as shown in fig. 9, for example, two

sections

51 and 52, the conveying speed of the front section 51 close to the first conveying line 3 is higher than that of the first conveying line 3, and the conveying speed of the rear section 52 far away from the first conveying line 3 is higher than that of the front section 51.

Further, as shown in fig. 6 to 10, the single piece separating apparatus further includes an abnormality recognition device 6, and the abnormality recognition device 6 is connected to a control device (not shown) which connects and controls the edge-approaching conveyor line, the first conveyor line, the reverse edge-approaching conveyor line, the second conveyor line, and the third conveyor line to be coaxial.

The abnormality recognition device 6 is configured to collect basic data, such as image signals, analog signals, and the like, which is required by the control device and used for determining whether parallel packages exist on the first conveying line 3, and the control device determines, according to the basic data acquired by the abnormality recognition device 6, a concurrent signal to control the working states of the narrow belt conveying line 31 and the deflection wheel/ball sorting machine 33.

Here, parallel parcel means that the parcel that is close to reverse limit machine one side on the first transfer chain 3 has the coincidence with at least one parcel that is close to the outside on the first transfer chain 3, and at this moment, just can't guarantee that the parcel is carried the rear one by one.

The abnormality recognition device 6 may be an image acquisition device disposed above the first conveyor line 3, the image acquisition device may be various cameras, CCD modules having photographing functions, or even a smart phone, a tablet computer, or the like, and a lens coverage area thereof covers at least a front half portion of the first conveyor line 3, preferably the first conveyor line 3.

In another embodiment, the abnormality recognition device 6 may also be a laser sensor and/or a photoelectric sensor (capable of measuring distance) disposed above the first conveying line 3, and a plurality of the laser sensors and/or photoelectric sensors are arranged in a straight line from one side of the first conveying line 3 to the other side, when the sensing distance of at least one laser sensor and/or photoelectric sensor in the middle is unchanged, and the sensing distances of the plurality of sensors on both sides of the laser sensor and/or photoelectric sensor are reduced relative to the initial distance when no package is present, it can be considered that two packages are present on the first conveying line 3 in parallel, but this way requires a large number of sensors, and the detection accuracy is slightly worse than the visual recognition.

Further, it is preferable that the abnormality recognition device 6 is provided in the front half or in the middle of the first conveyance line 3 so that the deflecting wheel/ball sorter 33 has a sufficient distance and time to adjust when it is confirmed that there is a parallel parcel.

The control device may be a known control device, such as a combination of a PLC and an industrial computer, or a separate PLC system, and the specific control software thereof may be compiled according to the control flow to be implemented, which is not the key point of the present solution and is not described herein again.

In addition, since the size of the parcels entering the edge-abutting machine 2 is not constant, for some large parcels, the center of gravity tends to be located outside the first conveying line 3, and therefore the parcels fall into the reverse edge-abutting machine 4 and cannot be conveyed, which results in a limited application range.

In view of this, as shown in fig. 11, in order to be able to convey large packages, a third conveyor line 7 is also arranged side by side outside the reverse side edge bearer 4, and the conveying surface of the third conveyor line 7 is flush with the conveying surface of the first conveyor line 3.

Moreover, the two sides of the reverse side-leaning machine 4 have a height difference, the conveying surface of the first side of the reverse side-leaning machine is located below the conveying surface of the first conveying line 3, the conveying surface of the second side of the reverse side-leaning machine is matched with the conveying surface of the third conveying line 7, namely, one side, connected with the third conveying line, of the conveying surface of the reverse side-leaning machine 4 is higher than the other side of the conveying surface of the reverse side-leaning machine, and at the moment, when large packages are erected on the first conveying line 3 and the third conveying line 7 to be conveyed, the reverse side-leaning machine 4 cannot interfere with the conveying of the large packages.

The third conveyor line 7 and the second conveyor line 5 may have the same or different structures, and are preferably roller conveyor lines, and meanwhile, the width of the third conveyor line 7 is smaller than that of the first conveyor line 3.

In addition, the input of second transfer chain 5 at least with reverse side by edge machine 4 half links up, and preferably, the input of second transfer chain 5 still links up with the output of third transfer chain 7 to can support the major possession parcel more effectively, guarantee effectual transport.

However, in special cases, for example, when a large package is in parallel relationship with a package on the first conveyor line 3, it is necessary to move the large package out of the second conveyor line 5, so as to ensure that the package parallel to the large package can be output out of the second conveyor line 5 separately. At the same time, a few parcels conveyed by the reverse side edge detector 4 and the third conveyor line 7 to the second conveyor line 5 may be output to the second conveyor line 5, affecting individual conveyance.

Then, as shown in fig. 11, a blanking roller 8 is provided on the second conveyor line 5 on a side close to the third conveyor line 7, and the blanking roller 8 is driven by a power source. For example, the blanking roller 8 can be driven by an external motor via a transmission mechanism. In a preferred embodiment, the blanking roller 8 is a roller with a built-in motor, so that the overall structure can be effectively simplified, and the length of the blanking roller can be as long as that of the second conveying line 5, or can only extend from the input end to the output end of the second conveying line 5 for a certain distance, and preferably does not exceed half the length of the second conveying line 5.

In another embodiment, as shown in fig. 11, the blanking roller 8 may be multiple segments 71, 72, and the length of each segment is equivalent to the length of each

segment

51, 52 of the second conveyor line 5, so that the start and stop of each segment of the blanking roller can be controlled separately, and when a large package passes through separately, the stop time of the blanking roller 8 can be reduced, thereby avoiding the influence on the output of the subsequent package to the outside. And the conveying speed of the blanking roller 8 is higher than that of the second conveying line, so that the parallel large package can be effectively blanked.

When the equipment works, the blanking roller 8 is driven to rotate by a power source under a normal state, and at the moment, the packages conveyed to the second conveying line 5 by the reverse side abutting machine 4 and the third conveying line 7 are occasionally moved out of the second conveying line 5, so that interference is avoided.

Further, as shown in fig. 12, a sliding groove 9 is provided on the outer side of the second conveyor line 2 and the third conveyor line 7, the sliding groove 9 is engaged with the side surface of the conveying surface of the return wire 10, the output end of the return wire 10 is engaged with the upper envelope 1 conveying the envelope to the edge detector 2, the return wire 10 may be any known conveying device, such as a section of linear conveyor 101 and a section of turning machine 102 wrapping the envelope, and the output end of the turning machine 102 is engaged with the side surface or the input end of the conveying surface of the upper envelope 1.

Finally, in other embodiments, at least one stage of slope conveyor line (not shown) may be provided between the input ends of the upper wrapping wire 1 and the edge-abutting machine 2, so that the stacked parcels can be separated by the slope conveyor line 20.

When the single piece separating equipment works, the method comprises the following steps:

and S1, manually or through an automatic device, pouring a plurality of parcels onto the upper covering wire 1, and moving a large number of parcels along with the upper covering wire 1 to the side edge approaching machine 2 at a first conveying speed.

And S2, enabling the parcels to enter the edge abutting machine 2 to abut against the edge of the side where the first conveying line 3 is located and move forwards at a second conveying speed, wherein the second conveying speed is higher than the first conveying speed.

S3, the parcel entering the first conveyor line 3 moves toward the second conveyor line 5 at a third conveying speed, and the third conveying speed is higher than the second conveying speed.

S4, the parcels entering the second conveyor line 5 are conveyed at a fourth conveying speed, which is higher than the third conveying speed.

And S5, the parcels which do not enter the first conveying line 3 enter the reverse side leaning machine 4 and lean against the opposite side.

Here, through the conveying speed who constantly improves different transfer chain to can make the parcel that has certain stack relation from top to bottom through the speed difference between two adjacent transfer chains can be separated, can solve among the prior art and need solve superimposed parcel's problem through climbing the transfer chain. Meanwhile, the distance between the packages can be pulled open by utilizing the speed difference of different conveying lines, even if the condition that part of the packages are parallel still exists on the edge-approaching machine 2, the problem of parallel packages can be basically solved by pulling the distance for multiple times after the packages are accelerated for multiple times, and the method can be suitable for separating single packages of most packages.

However, there may occasionally be some parallel package output, so the step of S3 may further include the following steps: the control device determines whether parallel packages exist on the first conveying line 3 according to the data collected by the abnormality recognition device 6 to control each narrow-band conveying line 31 to work so that the packages on the first conveying line 3 are output one by one, wherein the output one by one means that the next package starts to be output after the first package on the first conveying line 3 completely leaves the first conveying line 2.

The specific process is as follows:

and S31, the parcels enter the first conveying line 3 and are conveyed through the abnormality recognition device 6 to confirm whether the parcels are parallel, taking a camera as the abnormality recognition device as an example, the camera collects images of the parcels on the conveying surface of the first conveying line 3 and sends the images to the control device for image analysis (the image analysis method is a known technology, is not an innovative key point of the scheme, and is not described herein in detail), so that whether two parcels are parallel is determined.

S32, when the parallel parcels exist, each narrow belt conveying line 31 is restarted after being changed in speed and/or stopped for a period of time so that all parcels on the first conveying line 3 are dislocated, and then normal conveying is resumed.

In an alternative embodiment, the control device determines the narrow-band conveying line where the parcel is located by the image collected by the abnormality recognition device 6, as shown in fig. 13, calculates the distance L1 between the outer parcel 20 (here, the "inner side" refers to the side of the first conveying line far away from the reverse side approaching machine) and the previous parcel 00 in the parallel parcels and the length of the inner parcel 30 (here, the "outer side" refers to the side of the first conveying line near the reverse side approaching machine), judges the length of the distance L1 and the length of the inner parcel, calculates the distance L2 between the front end of the inner parcel 30 and the tail of the previous parcel of the outer parcel 20 if the distance L1 is greater than the length of the inner parcel 30, determines the speed to which the inner parcel 30 is accelerated and/or the speed to which the outer parcel is decelerated and the time required for the adjusted speeds when the inner parcel moves to the tail of the previous parcel 20, the control device sends a control signal to the corresponding narrow-band conveying line for adjustment, so that after the inner side package 30 moves to the position between the outer side package 20 and the previous package, the adjusted narrow-band conveying line restores the initial running state, and therefore complete dislocation of the inner side package 30 and the outer side package 20 is achieved.

If the distance L1 is less than the length of the inner side parcel 30, it is also possible to stop the narrow strip conveyor line on which the outer side parcel 20 is located after a parcel before the outer side parcel 20 enters the second conveyor line 5, and restart the narrow strip conveyor line on which the outer side parcel 20 is located when the end of the inner side parcel 30 moves to the front of the front end of the outer side parcel 20 parallel thereto, so that the inner side parcel 30 and the outer side parcel 20 are completely misaligned and are sequentially output to the outside of the first conveyor line 3.

And when judging whether the previous parcel leaves the first conveying line, the judgment can be carried out through the image collected by the abnormity identification device, for example, when the parallel parcels are confirmed, the distance from the tail end of one parcel in front of the outer parcel in the parallel parcels to the output end of the first conveying line is analyzed through the image, and according to the conveying speed of the current directional conveying line, the time for which the parcel can leave the first conveying line can be calculated. Of course, it is also possible to determine whether the package leaves the first conveying line by a sensor at the output end in combination with package tracking, which is a known technology and will not be described in detail herein.

And S33, when determining that the parallel packages do not exist, conveying each narrow belt conveying line 31 at the same speed.

In the embodiment with the deflecting wheel/ball sorter 33, the separation of the individual pieces can be ensured in other ways than by the complete misalignment of the packages, which can be achieved in the manner of step S32. Namely, the method comprises the following steps:

and S310, the parcels enter the first conveying line 3 to be conveyed and pass through the abnormity identification device 6 to confirm whether the parcels are parallel.

S320, when the control device confirms that there are parallel parcels, as shown in fig. 14, the inner parcel 30 is located on the deflecting wheel/ball conveying line 32, at this time, the narrow belt conveyor where the outer parcel 20 is located conveys normally, and the control device signals the deflecting wheel/ball conveying line 32 to change the direction to output the inner parcel 30 to the reverse side-approaching machine 4 side to the reverse side-approaching machine 4 and then reset, and the inner parcel 30 is output to the chute 9 along with the reverse side-approaching machine 4 to enter the return line 10 and return to the upper parcel 1.

In particular, the deflection of the part of the deflection wheel/ball in front of the inner item of baggage 30 may be reversed, and the control of the deflection may be determined by tracking the position of said inner item of baggage 30 on the conveyor line, for example by image analysis or known sensor tracking or encoder tracking, and thus determining which deflection wheel/ball to deflect. Or when the parallel parcels exist, the front of the inner side parcel can be rotated by a set distance and a set number of deflection balls/wheels. It is of course also possible to deflect all deflection wheels of the entire deflection wheel/ball transport line 32 to the same side. After the deflection is finished, the reset can be carried out within a preset time, and the recovery can also be carried out after the parcel is confirmed to enter the reverse side-approaching machine 4 through the image recognition device, wherein the reset is known in the prior art and is not described in detail.

S330, when the control device confirms that there is no parallel parcel, the deflecting wheel/ball conveying line 32 and the plurality of narrow strip conveying lines 31 are conveyed while maintaining the same direction and conveying speed, that is, the wheel/ball conveying line 32 and the plurality of narrow strip conveying lines 31 are maintained in a normal conveying state.

Further, when separating, there are some packages that can be erected on the first conveyor line 3 and the third conveyor line 7, and since the blanking roller 8 normally keeps the state of rotating to the outside of the second conveyor line 5, when a large package is conveyed to the second conveyor line 5, the blanking roller 8 needs to be stopped so as to avoid being transplanted outside the second conveyor line 5, therefore, the step S3 includes the following steps: the control device determines whether a large package 40 is erected on the first conveyor line 2 and the third conveyor line 7 according to the data of the abnormality recognition device 6, and if it is determined that there is no large package 40, S6 is executed; when it is judged that there is the large parcel 40, S7 is executed.

And S6, controlling the blanking roller 8 to keep normal conveying blanking by a control device.

And S7, when the large packages are conveyed to the second conveying line 5, the control device controls the blanking roller 8 to stop rotating until the large packages move to the outside of the blanking roller 8, and then the rotation is recovered. The specific time of the large package entering the second conveyor line 5 and being output to the outer side of the output end of the blanking roller 8 can be determined by various known methods, for example, the distance from the large package to the corresponding position is calculated by image recognition, and the determination can be performed by combining the running speed of each conveyor line, which is a known technology and is not described in detail herein.

Further, when it is determined that there is a large package 40, there is also a case where there is a small package 50 on the first conveying line 3 in parallel with the large package 40, and therefore, in order to avoid parallel conveying caused thereby, the step S3 also wraps the following process: when it is determined that there are large packages on the first conveyor line 3 and the third conveyor line 7, identifying whether there are packages on the first conveyor line 3 that are parallel to the large packages; if it is determined not to exist, performing S8; if it is determined that there is a package parallel to the big package, S9 is performed, as shown in fig. 15.

S8, the control device controls the blanking roller to stop when the large package moves to the second conveying line, and when the large package moves out of the far end of the blanking roller, the blanking roller resumes rotating blanking;

and S9, the control device controls the blanking roller to keep rotating so as to blank towards the outer side of the second conveying line.
