Description

Rotary roller deflection type sorting device and logistics sorting system

Technical Field

The invention relates to the field of logistics equipment, in particular to a rotary roller deflection type sorting device and a logistics sorting system.

The goods reversing mode in the modern automatic intelligent sorting system mainly comprises a swing arm type, a turning plate type, a rotating disc type, a pushing head type, a sliding block type, a deflection type and the like.

The deflection sorting includes deflection wheels, deflection balls, deflection conveyer belts, etc. for example, chinese patent No. 201721094362.7 discloses a roller type steering transfer machine, which is a deflection wheel type, in which the rollers are rotatably disposed on a deflection base, the deflection base is rotatable, and the rotation of the deflection base drives the rotation of the rollers, thereby realizing the steering of the object passing through the rollers.

The problem with this configuration is that: each roller needs a deflection seat, and the increase of the number of the rollers causes the increase of the number of the deflection seats, thereby resulting in complex structure and great weight. And the special structure design of each deflection seat also increases the clearance between the deflection wheels, and increases the risk of material jamming.

In addition, in the structure, the roller is driven to be connected with the second transmission shaft 71 through the O-ring, but because the roller is fixed on the offset seat and rotates along with the offset seat, the O-ring needs to be twisted and deformed after the roller deflects, and the O-ring cannot be continuously transmitted after being twisted, so that the roller cannot be continuously driven to rotate by the O-ring after rotating along with the offset seat, and the conveying of the article cannot be realized.

Meanwhile, the deflector holder rotates through two bearings, but the bearings are in a relative rotation mode of an inner ring and an outer ring, and the structure has the problem that the bearings are easy to damage when bearing large loads.

The belt-deflecting type sorting apparatus, such as the belt sorting apparatus disclosed in application No. 201910207235.0, has two belt sorting units on one deflecting base, which is advantageous for reducing the number of deflecting bases, but the belt is driven by a roller driving structure similar to the above-mentioned embodiment, and the above-mentioned problems also exist.

Meanwhile, the arrangement of the sorting units is unreasonable, and the gaps between the adjacent sorting units are large, so that the risk of material blockage is increased.

Detailed Description

Objects, advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments. The embodiments are merely exemplary for applying the technical solutions of the present invention, and any technical solution formed by replacing or converting the equivalent thereof falls within the scope of the present invention claimed.

In the description of the schemes, it should be noted that the terms "center", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not 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 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 following describes the roller-deflecting sorting apparatus according to the present invention with reference to the accompanying drawings, as shown in fig. 1 and fig. 2, which includes a frame 1000, wherein the frame 1000 includes a supporting leg 1100, a fence 1200 and a top plate 1300. The supporting legs 1100 are four and distributed in a quadrilateral shape, and of course, the number of the supporting legs 1100 may be more.

As shown in fig. 1, each of the support legs 1100 may include a vertical column 1110 and a leg base 1120, the vertical column 1110 is disposed on the leg base 1120 in a height-adjustable manner, that is, waist-shaped holes 1121 are formed in the leg base 1120 and distributed along a longitudinal direction, a connection hole (not shown) corresponding to the waist-shaped hole 1121 is formed in the vertical column 1110, and the leg base 1120 and the vertical column 1110 may be connected to each other to fix the leg base 1120 and the vertical column 1110 by a bolt 1130 passing through the waist-shaped hole 1121 and the connection hole and then connecting a nut. The height of the pillar 1110 can be adjusted by adjusting the position of the connecting hole corresponding to the kidney-shaped hole. Of course, in other embodiments, the connection hole of the upright 1110 may also be a screw hole, and the bolt is screwed into the screw hole to connect the upright and the foot seat 1120.

As shown in fig. 1, the enclosure 1200 is integrally formed as a square sleeve body, which is erected on four of the supporting legs 1100, the top plate 1300 is square, which is fixed on the top of the enclosure 1200 and covers the upper opening of the enclosure 1200, as shown in fig. 3, a set of avoiding holes 1310 are formed on the top plate 1300 for installing the sorting units 2000, and the distribution of the avoiding holes 1310 is designed according to the distribution of the sorting units 2000.

As shown in fig. 1 and 2, each sorting unit 2000 has a structure capable of conveying articles thereon and is rotatable about a longitudinal axis X of its deflecting seat 100, and each sorting unit 2000 is connected to a deflecting drive device 3000 for driving the rotating about the longitudinal axis X. In operation, articles may be transported in a certain direction as they pass through the sorting unit 2000, and when the sorting unit 2000 is swung, the articles may continue to move in their initial direction of movement; when sorting unit 2000 deflects, the direction of movement of the articles as they pass through sorting unit 2000 is reversed to the direction to which sorting unit 2000 deflects.

In order to effectively achieve article diversion, as shown in fig. 3, the sorting units 2000 are arranged in a plurality of rows or columns, specifically, they are arranged in five rows, and each even-numbered row of sorting units 2200 is the same in number and one less than each odd-numbered row of sorting units 2100, i.e., each odd-numbered row has five sorting units 2100 and each even-numbered row has four sorting units 2200.

In addition, as shown in fig. 3, in order to reduce the gap between the sorting units 2000 as much as possible to ensure the sorting stability and avoid the jamming, each sorting unit 2100, 2200 of two adjacent rows is staggered and arranged closely, the sorting units 2100 of odd rows are in one-to-one correspondence, and the sorting units 2200 of even rows are in one-to-one correspondence. That is, each of the other sorting units is located between two sorting units of its adjacent row except for each odd-numbered row of sorting units 2100 located at both ends, and the rotation axes of the three sorting units are distributed in an equilateral triangle.

At this time, as shown in fig. 3, both ends of the even-numbered sorting units 2200 may be formed with a certain gap, which increases the risk of the jamming, and therefore, in a preferred embodiment, a set of supporting universal wheels or universal balls 4000, preferably a set of bull's eye universal balls, the tops of which are flush with the conveying surface of the sorting units 2200, are respectively provided at both ends of each even-numbered sorting unit 2200.

Generally, all the sorting units 2000 are rotatably disposed on a plate having an area close to the area enclosed by the enclosure 1200, but since the sorting units 2000 have a large weight, when an article passes through the sorting units 2000, the plate is subjected to an excessive load, and thus the plate is easily deformed, particularly, the plate is recessed toward the middle portion, after a long time use, which affects the position accuracy of the sorting units 2000. In a preferred embodiment, as shown in fig. 4, each row of sorting units 2000 is rotatably disposed on a carrier 1400 on the rack 1000, five rows of sorting units 200 are distributed on five carriers 1400, and two ends of each carrier 1400 are fixed on the opposite panels of the enclosure 1200.

As shown in fig. 5 and fig. 6, each sorting unit 2000 includes a biasing seat 100, the biasing seat 100 is rotatably disposed on the carrier 1400, and mainly used for providing a mounting space and a support for a structure thereon, and includes a rotation shaft 110, an axis of the rotation shaft 110 is a longitudinal axis X of the biasing seat 100, is perpendicular to the carrier 1400, and is fixed in an inner hole of a bearing 1500 on the carrier 1400, and an axis of the bearing 1500 is perpendicular to the carrier 1400, so that the biasing seat 100 can rotate relative to the carrier 1400.

In the above structure, since the eccentric base 100 and the structure thereon have a certain weight, and these weights are applied to the bearings (the bearings in which the inner and outer races rotate relative to each other) for rotating the eccentric base 100, the bearings are easily damaged. Then, as shown in fig. 6, the bearing 1500 is fixed in a sleeve 1610 of a bearing seat 1600, the sleeve 1610 vertically penetrates the carrier 1400 and is provided with a connecting plate 1620 at its outer periphery, the connecting plate 1620 is connected to the carrier 1400, a bearing 1700 is further provided at the top of the sleeve 1610, and the eccentric base 100 is provided on the upper rotating body 1710 of the bearing 1700. By adopting the structure, the gravity of the eccentric seat 100 and the structure thereon is mainly transmitted to the carrier plate 1400 by the bearing seat 1600, so that the bearing 1500 does not need to bear the gravity again or bear the gravity to be greatly reduced, thereby protecting the bearing 1500.

However, in another embodiment, the bearing 1500 is not necessary, as shown in fig. 7, that is, the deflector is directly coaxially fixed on the support bearing 1700, and the rotation shaft 110 thereof passes through the support bearing 1700, the support bearing 1700 is fixed on the bearing seat 1800 on the carrier plate, and the bearing seat 1800 is formed with a mounting groove for mounting the support bearing 1700 coaxially with the support bearing 1700.

As shown in fig. 5, a flat plate 120 is coaxially disposed on the rotation shaft 110, the flat plate 120 is circular or square, but may have other feasible shapes, preferably, a square is taken as an example, the four corners of the flat plate are provided with pillars 130, the pillars 130 are provided with mounting discs 140, the outer profile of the mounting discs 140 is approximately circular, a set of rotation rollers 200 with parallel axes and equal height is flatly disposed on the mounting discs 140, the height of a conveying surface 300 formed by the working surfaces of the set of rotation rollers 200 is slightly higher than the top surface of the eccentric seat 100 (i.e., the upper surface of the below-described cover disk 150) and the top plate 1300, the rotation rollers 200 may be integrally and rotatably disposed on the mounting discs 140, or shafts at two ends of the rotation rollers 200 are fixed on the mounting discs 140, and the rollers rotate relative to the shafts. Meanwhile, a cover circular plate 150 is disposed on the mounting plate 140, the height of the top surface of the cover circular plate 150 corresponds to the height of the top surface of the top plate 1300, and a rectangular hole 131 for each of the rollers 200 is formed in the cover circular plate 150.

Of course, in another embodiment, the plate 120 may not be provided with the mounting plate 140, the roller may not be provided on the mounting plate 140, the roller 200 is mounted on the channel on the plate 120, in this case, the roller body of the roller 200 may rotate relative to the shaft fixed to the channel 180, and the pillar 130 is directly provided with the covering circular plate 150.

When the conveying device works, articles on the rotating rollers 200 can be conveyed through the same-direction rotation of the rotating rollers 200, and when the rotating rollers 200 rotate horizontally, the articles passing through the rotating rollers can be turned, so that sorting is realized.

The number and size of the rollers 200 on each deflector base 100 can be designed according to different requirements, for example, when a plurality of rollers are disposed on one deflector base 100, the rollers 200 can be two relatively short and symmetrical rollers; or a long roller and two short rollers positioned in the middle of two sides of the long roller; or two symmetrical long rollers 210 and two short rollers 220 located at the middle positions of both sides thereof; of course, more short and long rolls are possible. Further alternatively, when two long rollers are mounted on the mounting plate 140, a certain space may exist in the area on both sides of the long rollers, and a universal ball may be provided in the space to fill the gap.

In other possible embodiments, as shown in fig. 8, only one roller 200 may be mounted on each of the deflector bases 100, in which case, the size of the whole deflector base 100 may be as small as possible, and the structure may be simplified, that is, the structure without the mounting plate 140 may be adopted, and the roller may be directly mounted by using a channel steel. In addition, when two short rollers 200 are mounted on each deflector base, the deflector base 100 having such a simplified structure can be used. However, as the structure of the deflector base 100 is simplified and the size is reduced, the number of the sorting units 2000 in the deflector sorting apparatus may be larger, for example, as shown in fig. 8, the sorting units 2000 are 7 rows and 7 columns, and in this case, two rows of the sorting units 2000 may be located on one carrier plate 1400.

In a preferred embodiment, as shown in fig. 9, two long rollers 210 with equal length and symmetry and two short rollers 220 with equal length and symmetry distributed on two sides of the long roller 210 are disposed on each of the mounting plates 140, the two short rollers 220 are located in a middle region of the long roller 210, and the four rotating rollers are disposed at equal intervals.

The roller 200 can be driven in various feasible manners, for example, when the number of the roller is 1, preferably, the roller is an electric roller, and at this time, the structure of the eccentric seat can be simplified, that is, only two channel steels for erecting the roller and covering circular plates fixed on the channel steels and the pillars need to be arranged on the flat plate.

When the number of the rotating rollers 200 is greater than or equal to 2, in an embodiment, one of the rotating rollers 200 is an electric roller, and the other rotating rollers 200 may be disposed on the mounting plate, and the electric roller is connected to and drives the other rotating rollers to rotate synchronously through a transmission mechanism, that is, the electric roller may realize the rotation of the other rollers through a transmission structure of an existing synchronous belt, a synchronous wheel or a chain wheel and a chain, and at this time, the plurality of rotating rollers 200 have the same length and have two parallel and level ends. Here, the specific structure of the motorized roller is a known technology, and is not a protection point of the present solution, and details are not described here.

In another embodiment, each of the rotating rollers 200 is a motorized roller.

In yet another embodiment, some of the rollers 200 are motorized rollers and others are driven directly or indirectly by drive rollers 400 parallel to their axes and driven by a power source. For example, when the number of the rotary rollers 200 is three, two rotary rollers 200 may be a set and rotatably mounted on the mounting plate, and they are directly or indirectly driven by one driving roller 400; another roller 200 may be a motorized roller 200.

In yet another possible embodiment, as shown in fig. 5, all the rollers 200 are arranged on the mounting plate and are driven directly or indirectly by a driving roller 400 parallel to its axis and driven by a power source. When the direct drive is performed, the roller surface of the driving roller 400 is in contact with the roller surface of the rotating roller 200, and when the driving roller 400 rotates, the rotating roller 200 rotates synchronously with the driving roller 400 under the action of friction force. When the indirect driving is adopted, the driving roller 400 drives the rotating roller 200 to rotate through the driving roller 500 which is in friction connection with the driving roller.

For example, when the number of the rollers 200 is 2, the driving roller 400 is located between the two rollers 200 and is in frictional contact with both of the rollers 200.

As shown in fig. 5, when the number of the rollers 200 is three or four, two adjacent rollers 200 may be in one set, and the remaining one or two rollers may be in one set, one set of the rollers 200 is in frictional contact with a driving roller 500, and both driving rollers 500 are in frictional contact with the driving roller 200. When the rotary rollers 200 are four, the rotary rollers 200, the driving rollers 500 and the driving rollers 400 are integrally distributed in an inverted triangle, so that the driving of the plurality of rotary rollers 200 can be realized by one power source.

As shown in fig. 5, the driving roller 400 and the driving roller 500 are mounted on the supporting seat 160 or the channel steel of the plate 120.

Since the continuous friction between the rotary roller 200 and the driving roller 500 and between the driving roller 500 and the driving roller 400 is required, the stability of the contact therebetween is relatively lowered due to the friction loss after a certain period of use, which affects the reliability of driving.

Therefore, in a preferred embodiment, it is desirable to form a stable frictional connection therebetween, and as shown in fig. 10, when the driving roller 400 directly drives the rotating roller 200, the driving roller 400 is self-adjusting frictionally connected to the rotating roller 200 by a self-adjusting device 600. Specifically, two ends of the driving roller 400 are respectively disposed on a lifting seat 610 on the flat plate 120, the lifting seat 610 is slidably disposed on two guide rails 620 which are disposed on two sides of the lifting seat and perpendicular to the flat plate, and a spring 630 which is in a compressed state in a normal state is further disposed at the bottom of the lifting seat 610, at this time, a reaction force of the spring 630 can provide a lifting force to the lifting seat 610, so that the driving roller 400 thereon can be continuously attached to the rotating roller 200.

When the driving roller 400 drives the rotating roller 200 through the driving roller 500, the driving roller 400 and the driving roller 500 are in self-adjusting friction connection and/or the driving roller 500 and the rotating roller are in self-adjusting friction connection. That is, as shown in fig. 11, the driving roller 400 can achieve its continuous effective engagement with the driving roller 500 by the adjustment means having the same structure as the above-described self-adjustment means 600. Meanwhile, the driving roller 500 also adopts an adjusting device with the same structure as the self-adjusting device 600 to realize the self-adjusting friction connection with the rotating roller 200.

Also, a power source for driving the driving roller 400 may be integrated in the driving roller 400 or provided outside thereof. For example, when the driving roller 400 may be a motorized roller, a power source is integrated into the driving roller 400. When the driving roller 400 is driven by an external power source, two ends of the driving roller are rotatably disposed on the supporting base, and one end of the driving roller is connected to a motor (not shown) disposed on the biasing base 100, wherein the motor may be a reduction motor with a reduction structure, and the motor may also be a common motor, and is connected to the driving roller 400 through a gear transmission or other known transmission structure.

Whether the rotating roller is an electric roller or the driving roller is an electric roller, the rotating roller 200 and the driving roller 400 need to be powered and communicated with an upper computer through a circuit 700, and the rotating roller 200 and the driving roller 400 need to rotate along with the deflection seat 100, so that the circuit 700 is inevitably interfered by deflection action, and in order to reduce interference, as shown in fig. 7, a routing channel 170 coaxial with the rotating shaft 110 and the flat plate 120 is formed on the rotating shaft 110 and the flat plate 120, and the circuit can penetrate into the routing channel 170 from the bottom of the rotating shaft and penetrate out of the flat plate 120 so as to be connected to the rotating roller 200 or the driving roller 400 on the deflection seat 100, so that the rotation of the deflection seat does not generate interference on the circuit 700 any more, and the stability of wiring is ensured.

Each of said sorting units 2000 may be driven by a separate yaw drive 3000, for example by connecting a motor to the rotation shaft 110 of the yaw deck 100 of each sorting unit 2000, but this is obviously disadvantageous for reducing the cost of components and energy consumption, and therefore, more preferably, a plurality of said sorting units are driven by one said yaw drive 3000. For example, the deflection structure disclosed in the applicant's filed application No. 201910265828.2.

More specifically, the five-row sorting unit 2000 is driven by two yaw drives 3000, one yaw drive 3000 driving two rows of sorting units, and the other yaw drive 3000 driving three rows of sorting units.

As shown in fig. 12 and 13, the deflection driving device 3000 for driving the two rows of sorting units includes a fixed motor 3100, a motor shaft of the motor 3100 is perpendicular to the conveying surface 300, the motor shaft of the motor 3100 is fixedly connected to one end of a driving arm 3200, the other end of the driving arm 3200 is pivotally connected to a middle portion of a driving plate 3300, two ends of the driving plate 3300 are respectively fixed with a slat 3400 perpendicular and parallel to the driving plate, two slats 3400 extend in a horizontal direction and are connected to each other by a connecting rod 3500 perpendicular to the slats, so that the driving plate 3300, the slats 3400 and the connecting rod 3500 form a fixed driving frame. Two of the slats 3400 are pivotally connected to the plate 120 of the deflector of the sorting unit 2000 in a row, and a shaft 3600 connecting the slats 3400 and the plate 120 is formed near one side edge of the plate 120, and a hole 3410 corresponding to each shaft 3600 is formed in the slat 3400. When the automatic sorting machine works, the motor drives the driving arm 320 to rotate around the motor shaft, so that the transmission frame formed by the transmission plate, the lath 3400 and the connecting rod 3500 is driven to integrally rotate without deformation, and the lath 3400 drives the sorting unit 2000 connected with the lath 3400 to rotate around the axis of the rotating shaft to realize deflection.
