Detailed Description

The objects, advantages and features of the present invention are illustrated and explained by the following non-limiting description of preferred embodiments. These embodiments are only typical examples of the technical scheme of the invention, and all technical schemes formed by adopting equivalent substitution or equivalent transformation fall within the scope of the invention.

In the description of the embodiments, it should be noted that the positional or positional relationship indicated by the terms such as "center", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "inner", "outer", etc. are based on the positional or positional relationship shown in the drawings, are merely for convenience of description and simplification of description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in the specific orientation, and thus are not to be construed as limiting the present invention. 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 scheme, the direction approaching the operator is the near end, and the direction separating from the operator is the far end, with reference to the operator.

The oscillating sorting system of the present disclosure is described below with reference to the accompanying drawings, as shown in fig. 1 and 2, and includes a conveyor line 5000, where the conveyor line 5000 may be a variety of possible linear conveyor devices, such as a belt conveyor, a roller conveyor, etc. The conveying line 5000 may be a conveying line extending for a sufficient length, or may be formed by sequentially connecting a plurality of conveying lines, which may be extended linearly, or may be extended in a curved manner, and the conveying line is specifically designed according to a specific application scenario, which is not limited herein.

As shown in fig. 1 and fig. 2, an input end and/or a side of the conveying line 5000 is provided with a packing table 9000, where the packing table 9000 is used to supply goods to the conveying line 5000, and the packing table 9000 may be a known DWS conveying line with weighing, volumetric and scan code reading routes. Of course, the packet supply station may just convey the goods to the conveying line 500, and a code scanning device may be disposed above the conveying line 5000 to scan the codes to obtain the route.

As shown in fig. 1 and fig. 2, the side edge of the conveying line 5000 is provided with a swing type sorting device positioned at the rear end of the bag supplying table 9000 and a sorting grid 6000 matched with each swing type sorting device. Preferably, a plurality of the swing type sorting devices are located on the same side of the conveying line 5000, and a plurality of the sorting grids 6000 are located on the other side of the conveying line 5000. When cargoes are sorted, when the cargoes move to the sorting lattice 6000 corresponding to the cargoes along with the conveying line 5000, the cargoes are pushed or hit to the sorting lattice 6000 from the conveying line 5000 by the reciprocating swing of the swing arm 100 of the swing type sorting device, so that sorting is achieved.

The swing type sorting device may be various devices for discharging by the reciprocating swing of the swing arm 100, for example, the structures of the swing type sorting device disclosed in application nos. 201811070546.9, 201821328697.5, 201420597745.6, etc.

However, in the above-mentioned swing type sorting device, since the length of the swing arm is often longer, and the distal end of the swing arm is usually free from a supporting structure, there is a tendency that the distal end of the swing arm sags under the action of its own weight (i.e. the swing arm is inclined downward from its rotating end to its distal end), and as shown in fig. 2, after the swing arm 100 swings open, it is often located above the conveying surface 5100 of the conveying line 5000 and keeps a small gap, so there is a problem that the distal end of the swing arm sags and contacts with the conveying surface 5100, which will seriously affect the normal swing of the swing arm and the stable conveying of the conveying line.

Thus, in a preferred construction, a pendulum type sorting apparatus of the following embodiment is employed, as shown in fig. 3-4, comprising:

a swing arm 100 which can horizontally rotate around an axis 200 perpendicular to a conveying surface 5100 of the conveying line 5000,

And a motor 300, the position of which is fixed and is connected with the swing arm 100 directly or through a transmission mechanism 400, and drives the swing arm 100 to rotate around the shaft 200.

And as shown in fig. 6 and 7, the bottom surface 110 of the swing arm 100 is inclined upwards from the proximal end (the end of the swing arm close to the shaft 200) to the distal end (the end of the swing arm far away from the shaft), and the height of the bottom surface 110 of the swing arm 100 is gradually increased from the proximal end to the distal end, so that the gap between the bottom surface 110 and the conveying surface of the conveying line is gradually increased, and even if the length of the swing arm 100 is longer and the distal end of the swing arm is inclined downwards (sags) by a small extent due to the lack of support, the bottom surface of the distal end region can maintain an effective gap with the conveying surface 5100, thereby avoiding the problem that the bottom surface of the swing arm is in contact with the conveying surface of the conveying line to interfere.

The above-mentioned state of the bottom surface 110 may be achieved in different manners, in a first possible manner, as shown in fig. 6, the extending direction of the swing arm 100 is parallel to the conveying surface 5100 of the conveying line 5000, and at this time, the bottom surface 110 of the swing arm 100 is made to be an inclined surface, i.e. the bottom surface of the swing arm 100 is an inclined surface inclined from the proximal end to the distal end of the swing arm.

In a second possible embodiment, unlike the bottom surface 110 of the above embodiment, as shown in fig. 7, the bottom surface 110 of the swing arm 100 is a plane parallel to the top surface 150 thereof, and in this case, the whole extending direction of the swing arm 100 may not be parallel to the conveying surface 5100 of the conveying line, that is, the swing arm 100 is tilted as a whole.

Of course, the above-described inclined state of the bottom surface 110 may also be achieved by a combination of the above-described two embodiments.

The following will focus on the description of the structure shown in the second embodiment described above:

The swing arm 100 may be a swing arm as used in known sorters, for example, it may be a flat piece of metal, alloy or hard plastic, although it may be of more complex design. The length of the swing arm 100 can be controlled to be about 1.5m as in the conventional swing arm, and in a preferred structure, the overall length of the swing arm 100 is controlled to be between 0.9 and 1.2m, and more preferably between 1.0 and 1.2 m. The length design can effectively meet the sorting requirements of cargoes with most sizes, simultaneously can effectively reduce the dead weight of the swing arm, reduce the probability of sagging of the far end of the swing arm, and can also improve the rigidity and strength of the swing arm and ensure the sorting reliability.

In a preferred embodiment, as shown in fig. 3-5, the swing arm 100 includes a main plate 160 and end plates 170 located at two ends of the main plate 160, at least one groove 121 is concavely formed on the outer surface 120 of the main plate 160, and the groove 121 may extend along the length direction of the swing arm 100 or may extend along the width direction of the swing arm. Preferably, the grooves 121 extend along the length direction of the swing arm 100, and the number of the grooves 121 is two, and during specific processing, the grooves 121 may be formed by punching the main board 160 by a punching device, may be formed by injection molding, or may even be formed by welding a plurality of boards, and the end surface of the main board 160 finally obtained is in a shape with concave-convex staggering.

In order to further increase the rigidity of the swing arm 100, as shown in fig. 3 to 5, a reinforcing rib 140 is adjustably provided at a back position of the swing arm 100, specifically, is connected to the back of the main plate 160 in a screw-connection manner. Of course, in other embodiments, the reinforcing ribs 140 may be mounted on the back of the main board 160 in a non-movable manner, such as by welding. The reinforcing ribs 140 preferably extend in the width direction of the swing arm, and of course, the reinforcing ribs 140 may be disposed obliquely. The reinforcing ribs 140 may be U-shaped grooves, T-shaped pieces, L-shaped pieces, triangular pieces, etc., which are plural in number and distributed at a half-width region near the distal end of the swing arm 100 to increase the structural strength of the distal end region of the swing arm.

When the swing arm 100 is directly driven by the motor 300, a motor shaft of the gear motor may be directly connected to one end of the swing arm 100, and the specific structure is similar to the structure shown in application number 201420597745.6. At this time, in order to avoid the swing arm 100 swinging or the impact of the swing arm 100 locking to the motor 300, the rotating shaft of the motor 300 may be connected to one end of the swing arm through an expansion sleeve (not shown in the figure), and at this time, the shaft around which the swing arm 100 works is the rotating shaft of the motor.

As shown in fig. 3 and 4, the motor 300 is fixed on the motor base 2000, the motor 300 is fixed to the motor base 2000 by a set of connectors 300, the connectors 3000 are connectors having screws, such as nuts, and the axial direction of the connector 3000 connected to the motor base 2000 by the motor 300 is perpendicular or approximately perpendicular to the swing arm in the contracted state, so that during the swing of the swing arm 100, the connector 3000 is stressed mainly by pressure, and is less subject to shearing force, and is not easily damaged.

To further ensure the stability of the screw connection, as shown in fig. 3, a set of the connection members 3000 in the upper and lower positions is further connected to the nut through a dental plate 2200 located at the rear surface of the connection plate 2100 of the motor housing 2000. The addition of dental plate 2200 enhances the overall stability of the connection of connector 3000.

Meanwhile, as shown in fig. 8, jackscrews 2300 are respectively disposed on both sides of the motor 300 to abut against the sides thereof, and the jackscrews 2300 are reciprocally disposed on the connection plate 2100 on the motor base 2000 along the axial direction thereof, thereby reinforcing the fixation of the motor 300.

The motor base 2000 is fixed on the frame of the conveying line 5000, so that the installation and arrangement of the swing type sorting device can be conveniently performed, and the installation rigidity is ensured.

As shown in fig. 3,4 and 8, when the motor 300 drives the swing arm 100 to swing through the transmission mechanism 400, the transmission mechanism 400 may be a crank-link mechanism, which includes a crank 410 connected to the motor 300, an outer end of the crank 410 is pivotally connected to one end of a push rod 420, the other end of the push rod 420 is pivotally connected to a support shaft 430, the support shaft 430 is fixed on the back of the swing arm, a proximity switch 4000 is disposed above the transmission mechanism 400, the proximity switch 4000 is disposed on an arc-shaped slot 2400, the arc-shaped slot 2400 is disposed on a stand 2500 on the motor base 200, the position of the proximity switch 4000 on the arc-shaped slot stand 2400 is adjustable, and the proximity switch 4000 is located above the rotation track of a pivot 440 where the crank 410 and the push rod 420 are commonly connected.

The transmission mechanism 400 needs to be connected to the back (the side facing away from the conveying line 5000) of the swing arm 100, so, as shown in fig. 3 and fig. 4, a connection bracket 500 for connecting the transmission mechanism 400 is further provided on the back of the swing arm 100, and the connection bracket 500 may be integrally injection molded with the main board 160, or may be integrally connected with the main board 160 by welding or screwing.

The connection between the main board 160 and the connection bracket 500 is preferably performed by screwing, in which, as shown in fig. 3, connection holes 122 for connecting the connection bracket 500 are formed in the main board 160, and the connection holes 122 are located on the bottom plate of the groove 121, that is, a row of connection holes 122 is formed in each groove 121, and the connection holes 122 are distributed from one end of the groove 121 to the other end of the groove 12. The connection bracket 500 has thereon a connection with a portion of the connection

The holes 510 corresponding to the holes 122 are connected with nuts through a set of bolts respectively passing through the connecting holes 122 and the holes 510, so that the connection between the connecting bracket 500 and the main board 160 can be realized.

In order to further improve the assembly strength of the connection bracket 500 and the main board 160, as shown in fig. 5, a reinforcing plate 130 is further disposed in the groove 121, and the reinforcing plate 130 is fixed in the groove 121 by a bolt connecting the main board 160 and the connection bracket 500.

Meanwhile, as shown in fig. 3, the reinforcing rib 140 may be fixed on the back of the main board 160 through the connection hole 122 at the bottom of the groove 121 and the bolt and nut corresponding to the hole, and the position of the reinforcing rib 140 may be adjusted by adjusting the position of the connection hole 122 connected with the reinforcing rib 140, so as to adjust the rigidity of the swing arm.

Further, at least part of the connecting holes 122 are gradually increased in height from the proximal end to the distal end of the swing arm 100, that is, part or all of the connecting holes 122 are arranged from one end to the other end of the swing arm in an upward inclined manner. And each row of the holes 510 of the connection bracket 500 is disposed at the same height as the corresponding connection holes. Thus, after assembly, the connection bracket 500 may be disposed on the swing arm 100 at a slight angle (since the connection bracket 500 is less inclined, not shown), i.e., the proximal end of the connection bracket 500 (the end proximal to the shaft 200) may be slightly lower than the distal end thereof (the end distal from the shaft 200). At this time, the transmission 400 is separated upward when pushing force is applied to the connection bracket 500, thereby providing a certain support to the swing arm and reducing the risk of falling of the distal end of the swing arm.

When the motor 300 drives the swing arm via the transmission 400, the shaft 200 around which the swing arm 100 is wound is no longer the motor shaft of the motor, and in this case, the shaft 200 may be a shaft parallel to the motor shaft and connected to the proximal end of the swing arm, and in one embodiment, the shaft 200 is fixed and non-rotatable, so that the swing arm 100 may rotate relative to the shaft 200. Or in another embodiment, the swing arm 100 is fixed with the shaft 200, so that the shaft 200 can rotate, and the rotation of the shaft 200 drives the swing arm 100 to rotate.

Preferably, as shown in fig. 9, the swing arm 100 and the shaft 200 are fixed, the shaft 200 may rotate while the shaft 200 is disposed at the proximal end of the connection bracket 500, and both ends of the shaft 200 extend outside the upper and lower sides of the connection bracket 500. The shaft 200 and the connecting bracket 500 are integrally formed or welded together, so that the structure is simple to process, convenient to install, large in stress surface and high in overall strength.

In order to realize the rotation of the shaft 200, as shown in fig. 8 and 9, the shaft 200 is mounted on a bearing 600, the bearing 600 is fixed on the portion of the shaft 200 extending to the outside of the upper and lower sides of the connection bracket 500, the bearing 600 is fixed on a bearing block 700, the bearing 600 and the bearing block 700 may be assembled by two independent components or may be directly a bearing with a seat, and the bearing block 700 is fixed on a support 800.

Since the swing arm 100 is fixed to the bearing block 700 by the shaft 200, in order to further secure the swing arm 100 in an upwardly inclined state as a whole, as shown in fig. 9, the bearing block 700 is inclined to the support 800, i.e., the first side 710 of the bearing block 700 is lower than the second side 720. In a specific arrangement, the bearing seat 700 may be fixed to the support 800 by welding, and in other embodiments, the bearing seat 700 and the support 800 may be fixed in a tilting manner by screwing.

Specifically, at least two sets of mounting holes (not shown) are provided on the support 800, and the mounting holes are preferably two pairs, and two mounting holes of each pair are used for mounting one bearing seat 700, and one of the mounting holes of each pair is slightly higher than the other, specifically, the mounting hole near the first side 710 of the bearing seat 700 is lower than the mounting hole near the second side 720 of the bearing seat 700. And the two mounting holes 730 on the bearing housing 700 have the same height, so that when the bearing housing 700 is mounted to the support 800 by a connector and a nut including the screw 900, the bearing housing 700 assumes an inclined state and the diameter of the mounting holes is slightly larger than that of the screw 900.

Further, as shown in fig. 1 and 8, the axial direction of the screw 900 connected to the bearing block 700 and the support 800 is perpendicular or nearly perpendicular to the swing arm in the contracted state, so that the screw 900 is substantially subjected to a compressive force rather than a shearing force during the swing of the swing arm 100, and thus the screw 900 is less likely to exhibit a problem of breakage due to the shearing force.

In addition, in actual use, since the impact force of the swing arm 100 is transmitted to the screw 900 and the nut from the bearing block 700, the screw and the nut connected to the bearing block 700 and the support 800 may be loosened due to long-term vibration after long-term use. At this time, the bearing housing 700 may have loosening and tilting problems, thereby reducing the stability of swing of the swing arm 100 and easily causing further sagging of the distal end of the swing arm 100.

Accordingly, as shown in fig. 9, at least one jackscrew 1000 is disposed on the opposite first and second sides 710 and 720 of the bearing seat 700, and the jackscrews 1000 are reciprocally disposed on the support 800 along the extending direction thereof, preferably, two jackscrews 1000 having a height difference are disposed on two sides of the bearing seat 700, and the jackscrews 1000 can effectively limit the positions of two sides of the bearing seat 700, so as to reduce the problem of loosening and moving of the bearing seat 700 due to vibration. Meanwhile, when the swing arm 100 sags, the protruding length of the top thread 1000 at different positions may be adjusted to finely adjust the position of the bearing housing 700 so that the swing arm 100 maintains an upwardly inclined state.

In practical use, since most of the impact force of the swing arm 100 swinging needs to be borne by the support 800 where the bearing seat is located, as shown in fig. 9, the supporting strength of the support 800 is extremely important for stable operation of the device, preferably, the support 800 includes a channel steel 810 and a bottom plate 820, the channel steel 810 is in an H shape, the bottom of the channel steel 810 is welded with the bottom plate 820, and the bottom plate 820 is disposed on the motor base. And, a reinforcing seat 830 fixed between the bottom plate 820 and the channel steel 810 is provided at a side of the channel steel 810 facing away from the bearing 600, and the reinforcing seat 830 can effectively support the channel steel 810, thereby improving rigidity of the overall structure.

And a protective cover (not shown in the figure) is further arranged on the motor base, so that the swing type sorting device can be effectively protected.

As shown in fig. 1 and 2, a roller 7000 is driven by a power source between the sorting grid 6000 and the conveying line 5000, and the roller 7000 may be an electric roller or a motor outside the roller 7000 is driven by a transmission structure. The height of the top of the roller 7000 corresponds to the height of the conveying surface of the conveying line 5000. The motorized pulley 7000 can block the goods to a certain extent to reduce the speed of the goods when the goods are rapidly moved to the sorting lattice, thereby reducing the impact force when the goods enter the sorting lattice. Of course, in other embodiments, such as when the swing arms 100 sort the goods in some flexible sort, the drum 7000 may apply power to the goods moved thereto to effectively sort the goods into the corresponding sort pocket 6000 when the goods lack sufficient power to move into the sort pocket due to insufficient driving force applied to the goods by the swing arms 100.

Meanwhile, as shown in fig. 1, an encapsulation layer 7100 is disposed on the outer circumferential surface of the roller 7000, and the encapsulation layer 7100 can effectively increase friction between the roller and the goods, thereby buffering the power of the translation of the goods, reducing the impact force of the movement of the goods to the sorting lattice, and effectively moving the goods into the sorting lattice 6000 through the rotation of the roller 7000.

In actual sorting, as shown in fig. 1 and fig. 2, an edge runner 8000 is further disposed at the front end of the first swing-type sorting device, and the edge runner 8000 may be disposed between the bag supply table 9000 and the conveying line 5000. The sidecar 8000 moves the goods transported by the wrapping table 9000 to the side where the swing type sorting device is located, and transports the goods to the transport line 5000. Because the closer the swing arm 100 is to the goods, the smaller the force of the swing arm 100 driving the goods, and the closer the goods are to the swing arm through the sidecar 8000, the force of the swing arm pushing the goods can be effectively reduced.

As shown in fig. 1, a side of the sidecar 8000 to be leaned against is provided with a flange 8100 above a conveying surface thereof, the flange 8100 extends to the conveying line 5000, and an inner surface 8110 thereof is located in an outer edge 5110 of the conveying surface 5100 of the conveying line 5000, so that the movement of goods out of the edge of the conveying line 5000 can be effectively prevented.

Finally, in order to avoid that the goods close to the side cannot be effectively sorted due to the contact between the goods close to the side and the proximal end of the swing arm, as shown in fig. 9, a guide plate 840 is further provided at the proximal end of the swing arm 100, the guide plate 840 is preferably V-shaped, and the guide plate 840 can guide the goods close to the side in front of the swing arm 100, and the guide plate 840 is fixed at the side of the channel 810 of the support 800, so that the swing sorting device is closer to the conveying line 5000 to make the whole structure more compact.

When the swing type sorting system is adopted for sorting, the method can comprise the following steps:

s1, providing any swing type sorting system and goods to be sorted.

S2, determining that the routed goods enter the conveying line 500 and move along with the conveying line 500. At this time, the goods may be placed on the conveyor line 500 by a manual or automated device. When the goods are packed manually, the goods can be manually placed on the conveying line 500 after the code scanning gun reads the routes of the goods, or the bar codes of the goods are manually placed on the conveying line 500 or the package supplying table only towards the direction which can be read by the code reader, and then the code scanning device on the conveying line 500 or the package supplying table 8000 scans the codes to achieve the acquisition of the routes.

S3, before the swing type sorting device corresponding to the goods is started, the roller corresponding to the sorting grid is started and can drive the articles passing through the roller to move towards the sorting grid. The position of each cargo on the conveying line 500 can be known by tracking the position of each cargo after each cargo enters the conveying line 500, and the specific tracking method is a known technology and is not an innovation point of the scheme and is not described herein. When the position of the goods is found to be close to the sorting grid corresponding to the route, for example, the position of the goods can be set to be 10cm from the sorting grid corresponding to the target route in a program, or other feasible values, the upper computer signals to start a motor for driving the roller 7000 to work, the motor drives the roller to rotate at a certain speed, and at the moment, the rotating speed of the roller 7000 can be relatively low, so that a better deceleration effect is achieved.

S4, when the roller rotates, the goods continue to move to the corresponding swing type sorting device along with the conveying line 5000, and the upper computer signals to control the swing type sorting device to start to move the goods to the corresponding sorting grid direction;

s5, after the swing type sorting device finishes sorting, the upper computer controls the roller to stop rotating.

In the S2, if the position of the goods at the conveying line is far away from the swing arm, in the swing arm sorting process, the striking force applied by the swing arm to the goods is large, so in a more preferred embodiment, the goods conveyed by the manual or automatic equipment firstly pass through the side leaning machine 8000 to lean against the side where the swing sorting device is located and then enter the conveying line 5000, at this time, the distance between the goods and the swing arm is relatively close, and the pushing force of the swing arm to push the goods can be effectively reduced.

In S4, if according to the control process of conventional swing arm, then the swing arm sorts the goods with the mode of beating, and at this moment, the goods receives great impact force, appears the problem of damage easily, and the speed that the goods moved after being beaten also can be faster, has increased the risk of damaging when getting into the letter sorting check mouth. In the step S4, the motor of the swing type sorting device controls the swing arm to push the goods to the sorting lattice according to the multi-speed flexible control method, that is, the swing arm continuously applies the pushing force to the goods after contacting with the goods, so as to push the goods to the sorting lattice.

The multi-speed flexible control method is characterized in that the operation of the swing arm is controlled to comprise a first acceleration section, a first deceleration section, a second acceleration section and a second deceleration section, wherein the first acceleration section is in time, the swing arm swings outwards from a static state to a maximum speed, the first deceleration section is started when the swing arm is close to or just contacts with goods, at the moment, the swing arm continuously swings to a maximum opening position from a position of swinging to the maximum speed, the second acceleration section is started after the swing arm is opened to the maximum angle, at the moment, the swing arm is accelerated to swing to the maximum speed in the opposite direction, and at the second deceleration section, the swing arm starts to decelerate and continuously moves to a recovery position to stop when reaching the recovery position.

The swing arm is accelerated to the maximum speed in the first acceleration section, the driving force born by the swing arm is larger in the process, the swing arm is decelerated after the swing arm starts to decelerate, the driving force born by the swing arm is greatly reduced, the pushing force exerted by the swing arm on the goods is relatively smaller after the swing arm is contacted with the goods according to the transmission characteristic of the force, the goods cannot be separated from the swing arm immediately, then the swing arm can continuously push the goods to move towards the sorting grid opening along with the continuous swing of the swing arm, and the pushing force of the swing arm on the goods is smaller when the swing arm is continuously opened, the power of the goods when the goods is separated from the swing arm is further reduced, and the impact when the goods enter the sorting grid opening subsequently is reduced.

And according to the size of different objects, the running time of the swing arm in the first acceleration section and the first deceleration section can be controlled according to the needs, so that the swing arm is flexibly suitable for cargoes with different sizes, and a specific control method is a known technology and is not repeated.

After sorting is completed, the swing arm swings back in an accelerating way, and in order to avoid the shock of the swing arm to the motor and the crank connecting rod structure when the swing arm swings back to a certain position rapidly, the speed of the swing arm is reduced to zero in advance in a gradual way, so that the swing arm stops stably.

Of course, the flexible sorting method of S4 may be other possible methods, for example, the first deceleration section may be adjusted to a constant speed section, that is, the swing arm may be kept running at a constant speed after being swung out to reach a maximum speed.

The step S5 is for energy saving, so that the control process of the step S5 is not necessary, i.e. the drum may not stop until the sorting is completed after the start of the drum during the sorting.

Of course, in other embodiments, the control process of the drum is not required, i.e. in another swing sorting method, the following steps are included:

s10, providing the swing type sorting system and the goods to be sorted;

And S20, determining that the routed goods enter the conveying line and move along with the conveying line, wherein the step S20 can be the same as the step S2, and in the step S20, the goods enter the conveying line after passing through the edge leaning machine and leaning towards one side where the swing type sorting device is located.

And S30, moving the cargoes to the corresponding swing type sorting device, and controlling the swing arms to push the cargoes to the sorting grid by the motor of the swing type sorting device according to the multi-section speed flexible control method. The control process of S30 is the same as the above-mentioned S4 process, and will not be described here.

The invention has various embodiments, and all technical schemes formed by equivalent transformation or equivalent transformation fall within the protection scope of the invention.
