Swinging sorting device and swinging sorting system

Abstract

The present invention discloses a swing-type sorting device and a swing-type sorting system. The swing-type sorting device includes a swing arm that is horizontally rotatable about an axis, the bottom surface of the swing arm tilting upward from its proximal end to its distal end; and a motor that is fixed in position and connected to the swing arm directly or through a transmission mechanism, driving the swing arm to rotate about the axis. This solution configures the bottom surface of the swing arm to tilt upward from its proximal end to its distal end. Therefore, even if the distal end of the swing arm sags due to gravity, the distance between the distal end of the swing arm and the conveying surface is relatively close to the distance between the proximal end and the conveying surface under normal conditions. Therefore, the drooping distal end can still maintain an effective distance from the conveying surface, preventing contact between the swing arm and the conveying surface and ensuring stable operation of the device.

Description

Technical Field

[0001] The present invention relates to the field of logistics sorting equipment, in particular to a swing type sorting device and a swing type sorting system comprising the swing type sorting device. Background Art

[0002] The swing arm sorter uses a reciprocating swing arm to move the items on the conveyor line to the sorting grid on the side of the conveyor line to sort the goods.

[0003] Conventional swing arm sorting equipment usually includes a swing arm and a motor that drives it to swing. The motor can directly drive the swing arm to rotate, or it can drive the swing arm to rotate around an axis through a transmission mechanism. The specific structure can be the structure of the swing arm machine disclosed in application numbers 201811070546.9, 201821328697.5, 201420597745.6, etc.

[0004] However, in the aforementioned swing arm machines, the swing arm is often long, typically around 1.5 meters, and to ensure its rigidity, the weight of the swing arm is often relatively large. Furthermore, the swing arm is typically only provided with a support structure at the proximal end, with no support structure provided at the distal end. Consequently, the distal end of the swing arm is susceptible to sagging under its own weight. Since the swing arm will be located above the conveying surface of the conveyor line after swinging, and a small gap is maintained between the bottom of the swing arm and the conveying surface, the distal end of the swing arm may come into contact with the conveying surface after sagging. This contact with the conveying surface severely affects the effective swinging of the swing arm. Furthermore, the contact between the swing arm and the conveying surface of the conveyor increases wear on the conveyor belt, impacting the safety of the conveyor line. Summary of the Invention

[0005] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and to provide a swing type sorting device and a swing type sorting system including the above-mentioned swing type sorting device.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] Swing sorting device, including

[0008] a swing arm capable of horizontally rotating about an axis, wherein a bottom surface of the swing arm is inclined upward from a proximal end to a distal end;

[0009] The motor is fixed in position and is connected to the swing arm directly or through a transmission mechanism, and drives the swing arm to rotate around the axis.

[0010] Preferably, in the swing type sorting device, the swing arm is tilted as a whole and / or the bottom surface of the swing arm is an inclined surface.

[0011] Preferably, in the swing type sorting device, the length of the swing arm is between 0.9-1.2m.

[0012] Preferably, in the swing type sorting device, a reinforcing rib is provided on the back of the swing arm in an adjustable position.

[0013] Preferably, in the swing type sorting device, the swing arm is connected to the transmission mechanism via a connecting bracket integrally formed on the back of the swing arm or welded or screwed.

[0014] Preferably, in the swing type sorting device, at least one groove is formed on the outer surface of the swing arm, a row of connection holes is formed at the bottom of the groove, the connection bracket is screwed at the connection hole and a reinforcement plate is provided in the groove.

[0015] Preferably, in the swing-type sorting device, at least one row of connecting holes for installing a connecting bracket and arranged from the proximal end to the distal end of the swing arm is formed on the swing arm, and the height of at least part of the connecting holes in each row gradually increases from the proximal end to the distal end of the swing arm, and each row of holes on the connecting bracket does not have a height difference, so the connecting bracket can be tilted and arranged on the back of the swing arm, and the proximal end of the connecting bracket is lower than the distal end.

[0016] Preferably, in the swing-type sorting device, the shaft and the connecting bracket are integrally formed or welded together.

[0017] Preferably, in the swing type sorting device, the shaft is arranged on a bearing, and the bearing seat where the bearing is located is tiltedly arranged on a support.

[0018] Preferably, in the swing-type sorting device, the support includes a channel steel and a bottom plate, and the axial direction of the screw connecting the bearing seat and the support is perpendicular or approximately perpendicular to the swing arm in the retracted state.

[0019] Preferably, in the swing type sorting device, at least one top screw abutting against the bearing seat is respectively provided on two opposite sides of the bearing seat, and the top screw can be reciprocated and moved along the extension direction thereof on the support.

[0020] Preferably, in the swing type sorting device, the motor is fixed on a motor seat, and the axial direction of the connecting piece connecting the motor and the motor seat is perpendicular or approximately perpendicular to the swing arm in the retracted state.

[0021] Preferably, in the swing-type sorting device, the transmission mechanism is a crank-connecting rod mechanism, and a proximity switch is provided above the transmission mechanism.

[0022] The swing type sorting system comprises a conveying line, wherein the side of the conveying line is provided with any of the above-mentioned swing type sorting devices and a sorting grid matched with each of the swing type sorting devices.

[0023] Preferably, in the swing-type sorting system, a roller driven by a power source is provided between the sorting opening and the conveyor line.

[0024] The advantages of the technical solution of the present invention are mainly reflected in:

[0025] This solution sets the bottom surface of the swing arm to be inclined upward from the proximal end to the distal end of the swing arm. Therefore, even if the distal end of the swing arm droops due to gravity, since the distance between the distal end of the swing arm and the conveying surface is larger than the distance between the proximal end and the conveying surface under normal conditions, the drooping distal end can still maintain an effective distance from the conveying surface, avoiding contact between the swing arm and the conveying surface, thereby ensuring the stability of the equipment operation.

[0026] This solution can meet the sorting needs of most sizes of goods to the greatest extent through the design of the swing arm length. At the same time, it can reduce the weight of the swing arm and the risk of sagging at the far end of the swing arm. At the same time, it greatly improves the rigidity of the swing arm and ensures the reliability of sorting.

[0027] A groove is formed on the swing arm of this solution, and a reinforcement plate is provided in the groove and can be connected to the reinforcing ribs, which can further improve the rigidity of the swing arm itself and the overall structure of the connecting bracket. It is strong and durable and suitable for sorting various soft and hard goods.

[0028] The connecting bracket and the shaft of this solution are integrally formed or welded together, and the overall rigidity is strong, the processing is simple, the installation is convenient, the force-bearing surface is large, and the overall strength is high.

[0029] The connection hole for installing the connecting bracket on the swing arm of this solution is inclined from the proximal end to the distal end, so that the connecting device can be tilted upward after installation. Therefore, when a thrust is applied to the swing arm through the transmission mechanism, an upward component force can be generated to overcome the gravity of the swing arm itself, so that the swing arm can be kept in an upward tilted state, further reducing the probability of the distal end of the swing arm drooping and possibly contacting the conveyor line, thereby improving the safety of operation.

[0030] The tilting setting of the bearing seat of this solution can effectively keep the swing arm installed on the ride in a tilted state, and the bearing seat is limited by the top screw, which can ensure the stability of the bearing seat fixation and avoid the problem of loosening and movement of the bearing seat. At the same time, the installation state of the bearing seat can be fine-tuned by the top screw, so that the bearing seat can continue to maintain the tilted state to ensure that the swing arm remains tilted upward toward the far end.

[0031] The direction setting of the screw connecting the bearing seat and the support and the direction setting of the connecting piece connecting the motor and the motor seat in this solution can effectively prevent the screw and the connecting piece from being subjected to shear force, greatly reducing the risk of screw damage and ensuring the safety and stability of the overall structure.

[0032] The proximity switch of this solution is arranged above the crank-connecting rod mechanism. Therefore, even if the motor mounting screw is damaged and the motor is loosened from the motor seat, the problem of the proximity switch being crushed under the crank-connecting rod mechanism in the existing structure can be effectively avoided, thereby improving safety.

[0033] The addition of rollers to the sorting system of this solution can effectively combine flexible sorting technology, that is, the swing arm sorts goods by pushing rather than hitting, reducing the risk of damage to goods and improving safety. At the same time, the rubber layer on the roller can effectively buffer the horizontal movement of goods, preventing goods from directly rushing into the chute. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The objects, advantages, and features of the present invention are illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of the application of the technical solutions of the present invention, and any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

[0044] In the description of the scheme, it should be noted that the terms "center", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0045] The swing type sorting system disclosed by the present invention is described below with reference to the accompanying drawings. Figure 1 , Attachment Figure 2 As shown, it includes a conveyor line 5000, which can be various feasible linear conveying equipment, such as a belt conveyor, a roller conveyor, etc. The conveyor line 5000 can be a conveyor line extending for a sufficient length, or it can be formed by connecting multiple conveyor lines in sequence. It can extend in a straight line or in a curve. The specific layout form is designed according to the specific application scenario and is not limited here.

[0046] As attached Figure 1 , Attachment Figure 2 As shown, a package supply platform 9000 is provided at the input end and / or side of the conveyor line 5000. The package supply platform 9000 is used to supply goods to the conveyor line 5000. The package supply platform 9000 can be a known DWS conveyor line with weighing, volume measurement, and barcode scanning and routing functions. Of course, the package supply platform can also only supply goods to the conveyor line 500, while a barcode scanning device is provided above the conveyor line 5000 to scan the barcode to obtain the routing.

[0047] As attached Figure 1 , Attachment Figure 2 As shown, the conveyor line 5000 is equipped with a swing-type sorting device located at the rear end of the package supply platform 9000 and a sorting grid 6000 corresponding to each swing-type sorting device. Multiple swing-type sorting devices are preferably located on the same side of the conveyor line 5000, with multiple sorting grids 6000 located on the other side of the conveyor line 5000. During sorting, when goods move along the conveyor line 5000 to the sorting grid 6000 corresponding to their route, the swing arm 100 of the swing-type sorting device swings back and forth, pushing or knocking the goods from the conveyor line 5000 into the sorting grid 6000 for sorting.

[0048] The swing-type sorting device can be any device that realizes material unloading by the reciprocating swing of the swing arm 100, such as the structure of the swing-type sorting device disclosed in application numbers 201811070546.9, 201821328697.5, 201420597745.6, etc.

[0049] However, in the above-mentioned swing type sorting device, since the length of the swing arm is often long and the distal end of the swing arm is usually without a supporting structure, the distal end of the swing arm tends to sag under the action of its own gravity (that is, the swing arm tends to tilt downward from its rotating end to its distal end). Figure 2 As shown, after the swing arm 100 swings open, it is often located above the conveying surface 5100 of the conveyor line 5000 and maintains a small gap. Therefore, after the far end of the swing arm droops, there is a problem of contact with the conveying surface 5100, which will seriously affect the normal swinging of the swing arm and the stable conveying of the conveyor line.

[0050] Therefore, in a more preferred structure, the swing type sorting device of the following embodiment is adopted, as shown in the attached Figure 3 -Attached Figure 4 As shown, the swing type sorting device includes:

[0051] The swing arm 100 can rotate horizontally around an axis 200 perpendicular to the conveying surface 5100 of the conveying line 5000.

[0052] The motor 300 is fixed in position and is connected to the swing arm 100 directly or through a transmission mechanism 400 , and drives the swing arm 100 to rotate around the shaft 200 .

[0053] And, as attached Figure 6 , Attachment Figure 7 As shown, the bottom surface 110 of the swing arm 100 is inclined upward from its proximal end (the end of the swing arm close to the axis 200) to the distal end (the end of the swing arm away from the axis); since the bottom surface 110 of the swing arm 100 gradually increases in height from the proximal end to the distal end, the gap between the bottom surface 110 and the conveying surface of the conveyor line will gradually become larger. Even if the length of the swing arm 100 is long and the distal end of the swing arm tilts downward (droops) slightly under the action of gravity due to lack of support, the bottom surface of the distal end area can maintain an effective gap with the conveying surface 5100, thereby avoiding the problem of interference caused by the contact between the bottom surface of the swing arm and the conveying surface of the conveyor line.

[0054] The above-mentioned state of the bottom surface 110 can be achieved in different ways. In a first feasible way, as shown in the attached Figure 6 As shown, the extension direction of the swing arm 100 is parallel to the conveying surface 5100 of the conveying line 5000. At this time, the bottom surface 110 of the swing arm 100 is an inclined surface, that is, 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.

[0055] In a second feasible embodiment, the bottom surface 110 is different from the above embodiment in that it is an inclined surface. Figure 7 As shown, the bottom surface 110 of the swing arm 100 is a plane parallel to its top surface 150. At this time, the overall extension direction of the swing arm 100 can be made not parallel to the conveying surface 5100 of the conveyor line, that is, the swing arm 100 is tilted as a whole.

[0056] Of course, the above-mentioned inclined state of the bottom surface 110 can also be achieved by combining the above-mentioned two embodiments.

[0057] The following description will focus on the structure shown in the second embodiment:

[0058] The swing arm 100 can be used in various known sorting machines. For example, it can be a flat piece made of metal, alloy, or hard plastic. Of course, more complex designs are also possible. Its length can be controlled to approximately 1.5 meters, similar to conventional swing arms. In a preferred configuration, the overall length of the swing arm 100 is controlled between 0.9 and 1.2 meters, more preferably between 1.0 and 1.2 meters. This length design effectively meets the sorting requirements of most cargo sizes; it also effectively reduces the arm's deadweight, minimizing the risk of distal droop; and it also improves the arm's rigidity and strength, ensuring reliable sorting.

[0059] In a preferred embodiment, as shown in the attached Figure 3 -Attached Figure 5 As shown, the swing arm 100 includes a main board 160 and end plates 170 located at both ends of the main board 160. The outer surface 120 of the main board 160 is concavely provided with at least one groove 121. The groove 121 can extend along the length direction of the swing arm 100 or along the width direction of the swing arm. Preferably, the groove 121 extends along the length direction of the swing arm 100, and there are two grooves 121. During specific processing, the grooves 121 can be formed by stamping the main board 160 with a stamping device, or can be formed by injection molding, or even by welding multiple plates. The final end face shape of the main board 160 is a staggered concave and convex shape. This structure is conducive to improving the overall rigidity of the swing arm 100 and increasing its anti-deformation ability.

[0060] In order to further increase the rigidity of the swing arm 100, as shown in the attached Figure 3 -Attached Figure 5As shown, a reinforcing rib 140 is adjustably provided at the back of the swing arm 100, specifically, it is screwed to the back of the main board 160. Of course, in other embodiments, the reinforcing rib 140 can also be installed on the back of the main board 160 in a fixed position, such as by welding. The reinforcing rib 140 preferably extends along the width direction of the swing arm, and of course the reinforcing rib 140 can be arranged at an angle. The reinforcing rib 140 can be a U-shaped groove part, or a T-shaped part, or an L-shaped part, or a triangular part, etc., and there are multiple of them, and they are distributed in the half-width area close to the distal end of the swing arm 100 to increase the structural strength of the distal area of ​​the swing arm.

[0061] When the swing arm 100 is directly driven by the motor 300, the motor shaft of the reduction motor can be directly connected to one end of the swing arm 100. The specific structure is similar to the structure shown in patent application No. 201420597745.6. In this case, to prevent the swing arm 100 from swinging or locking and impacting the motor 300, the motor 300's rotating shaft can be connected to one end of the swing arm via an expansion sleeve (not shown). In this case, the axis around which the swing arm 100 rotates during operation is the motor's rotating shaft.

[0062] And, as attached Figure 3 , Attachment Figure 4 As shown, the motor 300 is fixed on the motor base 2000. The motor 300 is fixed to the motor base 2000 through a group of connecting parts 300. The connecting part 3000 is a connecting part with a screw, such as a nut. The axial direction of the connecting part 3000 connecting the motor 300 and the motor base 2000 is perpendicular or approximately perpendicular to the swing arm in the contracted state. Therefore, during the swinging process of the swing arm 100, the force applied to the connecting part 3000 is mainly pressure, and rarely shear force, and it is not easy to be damaged.

[0063] In order to further ensure the stability of the screw connection, Figure 3 As shown, the high and low sets of connectors 3000 also pass through a tooth plate 2200 located on the back of the connecting plate 2100 of the motor base 2000 to be connected to the nut. The addition of the tooth plate 2200 enhances the overall stability of the connection of the connector 3000.

[0064] At the same time, as attached Figure 8 As shown, top screws 2300 are respectively provided on both sides of the motor 300 to abut against its side surfaces. The top screws 2300 can be reciprocated along the axial direction thereof and are arranged on the connecting plate 2100 on the motor base 2000, thereby reinforcing the fixation of the motor 300.

[0065] The motor base 2000 is fixed on the frame of the conveyor line 5000, so that the installation and arrangement of the swing type sorting device can be conveniently performed and the rigidity of the installation is ensured.

[0066] As attached Figure 3 , Attachment Figure 4 , Attachment Figure 8 As shown, when the motor 300 drives the swing arm 100 to swing through the transmission mechanism 400, the transmission mechanism 400 can be a crank-connecting rod mechanism, which includes a crank 410 connected to the motor 300, the outer end of the crank 410 is pivotally connected to one end of a push rod 420, and the other end of the push rod 420 is pivotally connected to a support shaft 430, and the support shaft 430 is fixed on the back of the swing arm, and a proximity switch 4000 is arranged above the transmission mechanism 400, and the proximity switch 4000 is arranged on the arc groove 2400, and the arc groove 2400 is arranged on the stand 2500 on the motor seat 200, and the position of the proximity switch 4000 on the arc groove bracket 2400 can be adjusted, and the proximity switch 4000 is located above the rotation trajectory of the pivot 440 to which the crank 410 and the push rod 420 are commonly connected.

[0067] The transmission mechanism 400 needs to be connected to the back of the swing arm 100 (the side facing away from the conveyor line 5000). Figure 3 , Attachment Figure 4 As shown, a connecting bracket 500 for connecting to the transmission mechanism 400 is further provided on the back of the swing arm 100. The connecting bracket 500 can be integrally injection-molded with the main board 160, or can be integrally connected to the main board 160 by welding or screwing.

[0068] It is preferred to connect the main board 160 and the connecting bracket 500 by screw connection. Figure 3 As shown, the main board 160 is provided with connection holes 122 for connecting the connection bracket 500, and the connection holes 122 are located on the bottom plate of the groove 121, that is, each groove 121 is provided with a row of connection holes 122, and the connection holes 122 are distributed from one end of the groove 121 to the other end of the groove 121.

[0069] The hole 510 corresponding to the hole 122 can be connected by a set of bolts and nuts passing through the connection hole 122 and the hole 510 respectively to achieve the connection between the connection bracket 500 and the mainboard 160.

[0070] In order to further improve the assembly strength of the connecting bracket 500 and the main board 160, as shown in the attached Figure 5As shown, a reinforcing plate 130 is further provided in the groove 121 , and the reinforcing plate 130 is fixed in the groove 121 by bolts connecting the main board 160 and the connecting bracket 500 .

[0071] At the same time, as attached Figure 3 As shown, the above-mentioned reinforcing rib 140 can also be fixed to the back side of the main board 160 by passing through the connecting hole 122 at the bottom of the groove 121 and the bolts and nuts on the corresponding holes thereon, and the position of the reinforcing rib 140 can be adjusted by adjusting the position of the connecting hole 122 connected to the reinforcing rib 140, thereby adjusting the rigidity of the swing arm.

[0072] Furthermore, the height of at least some of the connecting holes 122 gradually increases from the proximal end to the distal end of the swing arm 100, that is, some or all of the connecting holes 122 are arranged in an upwardly inclined manner from one end of the swing arm to the other end. Each row of holes 510 corresponding to the connecting holes on the connecting bracket 500 is arranged at the same height. Thus, after assembly, the connecting bracket 500 can be slightly tilted on the swing arm 100 (not shown in the figure because the tilt of the connecting bracket 500 is relatively small), that is, the proximal end of the connecting bracket 500 (the end closer to the shaft 200) will be slightly lower than its distal end (the end away from the shaft 200). At this time, when the transmission device 400 applies a thrust to the connecting bracket 500, it will produce an upward separation, thereby providing a certain amount of support for the swing arm and reducing the risk of the distal end of the swing arm falling.

[0073] When the motor 300 drives the swing arm through the transmission device 400, the shaft 200 around which the swing arm 100 rotates is no longer the motor shaft of the motor. In this case, the shaft 200 may be a shaft connected to the proximal end of the swing arm and parallel to the motor shaft. In one embodiment, the shaft 200 is fixed and cannot rotate, so that the swing arm 100 can rotate relative to the shaft 200. Alternatively, in another embodiment, the swing arm 100 is fixed to the shaft 200, so that the shaft 200 can rotate on its own, and the rotation of the shaft 200 drives the swing arm 100 to rotate.

[0074] In the preferred embodiment, as shown in the attached Figure 9 As shown, the swing arm 100 and the shaft 200 are fixed, and the shaft 200 is allowed to rotate. At the same time, the shaft 200 is arranged at the proximal end of the connecting bracket 500, and the ends of the shaft 200 extend outside the upper and lower sides of the connecting bracket 500. The shaft 200 and the connecting bracket 500 are integrally formed or welded together. This structure is simple to manufacture and install, has a large load-bearing surface, and has high overall strength.

[0075] In order to realize the self-rotation of the shaft 200, as shown in the attached Figure 8 , Attachment Figure 9As shown, the shaft 200 is set on the bearing 600, and the bearing 600 is fixed on the part of the shaft 200 extending outside the upper and lower sides of the connecting bracket 500, and the bearing 600 is fixed on the bearing seat 700. The bearing 600 and the bearing seat 700 can be assembled from two independent parts, or can be directly a bearing with a seat; the bearing seat 700 is fixed on the support 800.

[0076] Since the swing arm 100 is fixed on the bearing seat 700 through the shaft 200, in order to further ensure that the swing arm 100 is in an upward tilted state as a whole, as shown in the attached Figure 9 As shown, the bearing seat 700 is tilted on the support 800, that is, the first side 710 of the bearing seat 700 is lower than the second side 720. In a specific configuration, the bearing seat 700 can be fixed to the support 800 by welding; in other embodiments, the tilted fixing of the bearing seat 700 and the support 800 can also be achieved by screwing.

[0077] Specifically, the support 800 is provided with at least two groups of mounting holes (not shown in the figure), preferably two pairs of mounting holes. The two mounting holes in each group are used to mount a bearing seat 700. One mounting hole in 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. The two mounting holes 730 on the bearing seat 700 are at the same height. Therefore, when the bearing seat 700 is mounted on the support 800 via a connector including a screw 900 and a nut, the bearing seat 700 is tilted, and the diameter of the mounting holes is slightly larger than the diameter of the screw 900.

[0078] Further, as attached Figure 1 , Attachment Figure 8 As shown, the axial direction of the screw 900 connecting the bearing seat 700 and the support 800 is perpendicular or approximately perpendicular to the swing arm in the contracted state. Therefore, when the swing arm 100 swings, the screw 900 basically bears pressure rather than shear force. Therefore, the screw 900 is not prone to breakage due to shear force.

[0079] Furthermore, in actual use, the impact of the swinging arm 100 is transmitted from the bearing seat 700 to the screw 900 and nut. Therefore, after prolonged use, the screw and nut connecting the bearing seat 700 to the support 800 may become loose due to long-term vibration. In this case, the bearing seat 700 may become loose or skew, which will reduce the stability of the swinging arm 100 and easily cause the distal end of the swing arm 100 to sag further.

[0080] So, as attached Figure 9 As shown, at least one top screw 1000 is respectively provided on the first and second sides 710 and 720 of the bearing seat 700, which are in contact with the top screw 1000. The top screw 1000 can be reciprocated along its extension direction and is provided on the support 800. Preferably, two top screws 1000 with a height difference are respectively provided on both sides of the bearing seat 700. The top screws 1000 can effectively limit the position of the two sides of the bearing seat 700, thereby reducing the problem of loosening and movement of the bearing seat 700 due to vibration. At the same time, when the swing arm 100 sags, the extension length of the top screws 1000 at different positions can be adjusted to make fine adjustments to the position of the bearing seat 700 so that the swing arm 100 remains in an upward tilted state.

[0081] In actual use, since most of the impact force of the swing arm 100 needs to be borne by the support 800 where the bearing seat is located, as shown in the attached Figure 9 As shown, the support strength of the support 800 is extremely important for the stable operation of the equipment. Preferably, the support 800 includes a channel steel 810 and a base plate 820. The channel steel 810 is generally H-shaped, with the base plate 820 welded to the bottom of the channel steel 810. The base plate 820 is mounted on the motor base. Furthermore, a reinforcement seat 830 is provided on the side of the channel steel 810 facing away from the bearing 600, fixed between the base plate 820 and the channel steel 810. The reinforcement seat 830 can effectively support the channel steel 810 and improve the rigidity of the overall structure.

[0082] A protective cover (not shown in the figure) is also provided on the motor base to effectively protect the swing type sorting device.

[0083] As attached Figure 1 , Attachment Figure 2 As shown, a power-driven roller 7000 is provided between the sorting grid 6000 and the conveyor line 5000. The roller 7000 may be an electric roller or may be driven by a motor external to the roller 7000 through a transmission structure. The height of the top of the roller 7000 is equivalent to the height of the conveying surface of the conveyor line 5000. The electric roller 7000 can block the goods when they are moving rapidly toward the sorting grid, causing them to slow down, thereby reducing the impact force when they enter the sorting grid. Of course, in other embodiments, for example, when the swing arm 100 is sorting goods using certain flexible sorting methods, if the swing arm 100 does not exert sufficient driving force on the goods, resulting in the goods lacking sufficient power to move into the sorting grid, the roller 7000 can apply power to the goods moving onto it to effectively sort the goods into the corresponding sorting grid 6000.

[0084] At the same time, as attached Figure 1As shown, a rubber layer 7100 is provided on the outer circumferential surface of the drum 7000. The rubber layer 7100 can effectively increase the friction between the drum and the goods, thereby buffering the power of the translation of the goods, reducing the impact force of the goods moving toward the sorting grid, and can effectively move the goods to the sorting grid 6000 through the rotation of the drum 7000.

[0085] In actual sorting, if Figure 1 , Attachment Figure 2 As shown, a side shifter 8000 is also installed at the front end of the first swing-type sorting device. This side shifter 8000 can be positioned between the package supply platform 9000 and the conveyor line 5000. This side shifter 8000 shifts the goods conveyed by the package supply platform 9000 toward the side of the swing-type sorting device and onto the conveyor line 5000. Because the closer the swing arm 100 is to the goods, the less force it exerts on the goods; by keeping the goods close to the swing arm, the side shifter 8000 effectively reduces the force with which the swing arm pushes the goods.

[0086] As attached Figure 1 As shown, the side toward which the side-pull machine 8000 is to lean is provided with a side guard 8100 located above its conveying surface, and the side guard 8100 extends to the conveying line 5000 and its inner surface 8110 is located within the outer edge 5110 of the conveying surface 5100 of the conveying line 5000, thereby effectively preventing the goods from moving outside the edge of the conveying line 5000.

[0087] Finally, in order to avoid the goods coming into contact with the near end of the swing arm after being pulled to the side, which may cause ineffective sorting, as shown in the attached Figure 9 As shown, 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 to the front of the swing arm 100. The guide plate 840 is fixed to the side of the channel steel 810 of the support 800, so that the swing sorting device can be closer to the conveyor line 5000 to make the overall structure more compact.

[0088] When the swing sorting system is used for sorting, the following steps may be included:

[0089] S1, provide any of the above-mentioned swing sorting systems and goods to be sorted.

[0090] In step S2, the goods with a determined route enter the conveyor line 500 and move along it. At this point, the goods can be placed onto the conveyor line 500 manually or through automated equipment. When loading the goods manually, a barcode scanner can be used to read the goods' route and then place them onto the conveyor line 500 for transport. Alternatively, a barcode reader can simply position the goods on the conveyor line 500 or on the packaging platform, with the barcode facing the direction that can be read by the barcode reader. The barcode scanner on the conveyor line 500 or packaging platform 8000 then scans the barcode to obtain the route.

[0091] S3, before the swing sorting device corresponding to the goods is started, the roller at the corresponding sorting grid is started and can drive the items passing through it to move toward the sorting grid. After each cargo enters the conveyor line 500, its position will be tracked, so that the position of each cargo on the conveyor line 500 can be known. The specific tracking method is a known technology and is not an innovation of this solution, so it will not be described here. When it is found that the position of the cargo is close to the sorting grid corresponding to its route, for example, the distance between the cargo and the sorting grid corresponding to the target route can be set in the program at 10 cm, or other feasible values. The upper computer sends a signal to the motor driving the roller 7000 to start, and the motor drives the roller to rotate at a certain speed. At this time, the speed of the roller 7000 can be a relatively low speed, so as to achieve a better deceleration effect.

[0092] S4: When the roller rotates, the goods continue to move along the conveyor line 5000 to the corresponding swing sorting device. The upper computer sends a signal to control the swing sorting device to start moving the goods toward the corresponding sorting grid.

[0093] S5, after the swing sorting device completes sorting, the host computer controls the roller to stop rotating.

[0094] In said S2, if the position of the goods on the conveyor line is far away from the swing arm, the swing arm will exert a greater impact force on the goods during the swing arm sorting process. Therefore, in a more preferred embodiment, the goods transported by manual or automated equipment first pass through the side machine 8000 and lean towards the side where the swing sorting device is located before entering the conveyor line 5000. At this time, the distance between the goods and the swing arm is relatively close, which can effectively reduce the thrust of the swing arm to push and separate the goods.

[0095] In S4, if conventional swing arm control is used, the swing arm will sort the goods by striking them. This will subject the goods to a significant impact force, making them susceptible to damage. Furthermore, the goods will move at a higher speed after being struck, increasing the risk of damage upon entering the sorting slot. Therefore, in S4, the motor of the swing sorting device controls the swing arm using a multi-speed flexible control method to push the goods toward the sorting slot. Specifically, after the swing arm contacts the goods, it continuously applies a thrust force to push them into the sorting slot.

[0096] The multi-stage speed flexible control method controls the operation of the swing arm, including a first acceleration section, a first deceleration section, a second acceleration section and a second deceleration section. During the first acceleration section, the swing arm swings outward from a stationary state to a maximum speed. The first deceleration section starts when the swing arm is close to contacting the cargo or just contacts the cargo. At this time, the swing arm continues to swing from the position where it swings to the maximum speed to the maximum open position. The second acceleration section starts after the swing arm is opened to the maximum angle. At this time, the swing arm accelerates in the opposite direction to swing to the maximum speed. During the second deceleration section, the swing arm starts to decelerate and continues to move toward the recovery position until it stops when it reaches the retracted position.

[0097] Since the swing arm accelerates to the maximum speed in the first acceleration section, the swing arm is subjected to a large driving force during this process. After that, the swing arm begins to decelerate. At this time, the driving force exerted on the swing arm is greatly reduced. According to the force transmission characteristics, after the swing arm contacts the goods, the thrust exerted by the swing arm on the goods is also relatively small, and the goods will not be separated from the swing arm immediately. Subsequently, as the swing arm continues to swing, the swing arm can continue to push the goods toward the sorting grid; and since the swing arm is in a deceleration state when it continues to open, the thrust of the swing arm on the goods is also smaller, which further reduces the power of the goods when they are separated from the swing arm, and reduces the impact when they enter the sorting grid later.

[0098] Moreover, according to the size of different objects, the time for the swing arm to run in the first acceleration section and the first deceleration section can be controlled as needed, so as to flexibly adapt to goods of different sizes. The specific control method is a known technology and will not be described in detail.

[0099] After completing the sorting, the swing arm accelerates and swings back. In order to avoid the impact of the swing arm's rapid stop on the motor and crank-connecting rod structure, when the swing arm quickly swings back to a certain position, it slows down in advance so that the speed of the swing arm is gradually reduced to zero, thereby stopping stably.

[0100] Of course, the flexible sorting method of S4 may also be other feasible methods. For example, the first deceleration section may also be adjusted to a uniform speed section, that is, the swing arm maintains a uniform speed after reaching the maximum speed.

[0101] The step S5 is for energy saving considerations, therefore, the control process of the step S5 is not necessary, that is, during the sorting process, after the roller is started, it may not stop until the sorting is completed.

[0102] Of course, in other embodiments, the control process of the roller may not be required, that is, in another swing sorting method, the following steps are included:

[0103] S10, providing the swing type sorting system and goods to be sorted as described above;

[0104] S20, the goods with a determined route enter the conveyor line and move along the conveyor line; the step S20 here can be the same as the above-mentioned step S2, and in the said S20, the goods enter the conveyor line after passing the side machine and leaning towards the side where the swing sorting device is located.

[0105] At step S30, the goods are moved to the corresponding swing sorting device. The motor of the swing sorting device controls the swing arm according to the multi-speed flexible control method to push the goods to the sorting slot. The control process of step S30 is the same as the above step S4 and will not be repeated here.

[0106] The present invention has multiple implementation modes, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present invention.
