In some of the prior art, a rotary transfer device is disposed at the periphery of the sorting apparatus, a plurality of containers for receiving goods are stacked on a conveying device of the rotary transfer device, and after one container is full, the full container can be transferred by the conveying device and an empty container can be conveyed to a position for receiving goods. Wherein, a plurality of along the conveyor of radial distribution set up on the platform, the platform below sets up the gyro wheel, because the slewing transmission device diameter is great, the load is great, need a plurality of gyro wheels collaborative work, actually ground roughness is relatively poor simultaneously, because ground and platform are not two planes that are parallel completely, and the platform has certain rigidity, can't guarantee all supporting rollers all necessary wheel pressures, even in the one end of platform, the gyro wheel probably leaves ground, form the negative wheel pressure, cause slewing transmission device not evenly distributed's holding power, can't evenly bear the load. On the other hand, the self-weight of the large-area flat plate type platform with a certain thickness is larger, so that the required rotary inertia of the equipment is larger, and the required power and power consumption cost of the equipment are increased.

In some implementations, a slewing device 10 as shown in fig. 1 includes a plurality of conveyors 11 disposed on the upper side, and a platform 12 on the lower side, wherein a plurality of rollers 13 are disposed on the lower side of the platform 12, and the rollers 13 can move on the ground, so that the conveyors 11 on the upper side of the platform 12 can perform slewing motion.

However, in some practical situations, the diameter of the rotary transmission device 10 is large, for example, the diameter of some rotary transmission devices may be ten meters or more, due to the self-weight of the conveying device 11 and the platform 12, the inertia of the rotation is large, a large amount of power is consumed, and more rollers 13 are also needed to provide sufficient supporting force, while the rotary transmission device 10 sometimes needs to perform rotary motion under some severe working conditions, such as a slope of the ground causes a large height deviation, or a poor ground flatness and unevenness, each roller 13 has its own manufacturing deviation and assembly deviation, so that some rollers can contact with the ground and generate wheel pressure, while other rollers may form negative wheel pressure far from the ground, and the supporting function of the rollers is lost, and the rotary transmission device 10 is difficult to maintain the required height.

In order to solve the above problems, the present disclosure provides a rotary transmission device 20, and a sorting apparatus and a connecting assembly 100 applied to the rotary transmission device 20, to which the rotary transmission device 20 is applied.

As shown in fig. 2, the rotary transfer device 20 has a disk shape as a whole, and a conveying device 22 is provided to extend radially outward from the center for receiving and conveying sorted goods. The swing conveyor 20 may include a swing shaft 21, a plurality of conveying devices 22, and a connecting member 100.

Wherein, the revolving shaft 21 is located at the center of the revolving transmission device 20 and can be fixed on the ground or the working platform.

The plurality of conveying devices 22 may be extended radially outward from the center of the rotary conveying device to convey the goods, and the conveying devices 22 may be belt conveyors, chute conveyors, or other mechanisms for conveying, and can receive the goods conveyed by different upstream devices by rotating around the rotating shaft 21 to complete the sorting task. In practical applications, a plurality of containers for receiving the goods, such as cartons, may be stacked on each conveying device 22, the goods are received by the containers, and after a certain number of goods are received or the containers are full, the full containers are transferred to other positions for packaging or other operations by the conveying device 22, and meanwhile, another empty container is transferred to the receiving position to continue receiving the conveyed goods, so that the goods can be received without interruption, and the sorting efficiency is ensured.

The connecting assembly 100 is coupled to the underside of the conveyor 22 to avoid interference with the receipt and delivery of articles on the conveyor 22, to provide a relatively secure connection between all of the conveyors 22 to maintain the conveyors 22 relatively stable during pivoting, and also to provide for the transmission of pivoting drive to the conveyors 22, and the inner end of the first radial connecting member 111 near the center of the connecting assembly 100 may be coupled to the pivot shaft 21 by a bearing assembly to allow rotation about the pivot shaft 21. The bearing assembly may include an inner ring sleeved on the rotating shaft 21, and an outer ring rotatable with respect to the inner ring, and the outer ring may be fixedly connected with the plurality of first radial connecting parts 111 directly or through a connecting member. The number of first radial connecting members 111 may be the same as the number of conveyors 22, i.e. each conveyor 22 is connected to one first radial connecting member 111; the number of the first radial connecting members 111 may be smaller than that of the conveying device 22, and the conveying device 22 may be stably rotated about the rotation shaft 21 by a small number of the first radial connecting members 111. By connecting the plurality of conveyors 22 through the connecting assembly 100, the overall weight of the slewing transmission device 20 is reduced, and the power required for slewing is saved.

In an embodiment, the slewing conveying device 20 may further include a plurality of supporting wheels 23, the supporting wheels 23 may be disposed at the lower side of the conveying device 22, since the connecting assembly 100 is not a large-area flat plate structure, material is greatly saved, self weight of the connecting assembly 100 is also reduced, and the connecting assembly 100 itself does not need large rigidity. Meanwhile, the conveying device 22 may be a belt conveyor or the like, which has a relatively high self weight and may carry goods thereon, and thus, mainly focuses on the conveying device 22 in view of the overall weight distribution of the slewing device 20, and therefore, the supporting wheels 23 may be intensively disposed at the lower side of the conveying device 22 for supporting, reducing the number of the supporting wheels 23, and also improving the ability of the supporting wheels 23 to overcome adverse effects of the ground or the work table.

In one embodiment, the support wheels 23 are height adjustable. Through the height of adjusting supporting wheel 23 to adjust the whole height of gyration transmission device 20 or with the angle of horizontal plane, also can avoid the installation error of supporting wheel 23 simultaneously, or overcome the unevenness's on ground, table surface condition. Wherein the support wheel 23 may be adjustably connected to the underside of the conveyor 22 by means of screws, elastic structures or the like. The support member may be directly attached to the lower surface of the conveyor 22 or may be attached to the lower surface of the connecting member 100 located below the conveyor 22 to support the conveyor 22 having a relatively large weight.

The slewing gear 20 has been described above, and the coupling assembly 100 thereof will be described in detail below.

As shown in fig. 3 and 4, the connecting assembly 100 may include a plurality of inner assemblies 110, and a plurality of outer assemblies 120 disposed radially outward of the inner assemblies 110. The number of inboard assemblies 110 and outboard assemblies 120 may be determined based on the size of the carousel 20, the number and weight of conveyors 22, and the like.

The medial module 110 and the lateral module 120 may be provided as separate units, with a plurality of medial module 110 units connecting to form a structure for connecting the delivery device 22 near the center, and a plurality of lateral module 120 units connecting to form a structure for connecting the delivery device 22 far from the center. Meanwhile, the inner assembly 110 and the outer assembly 120 can be arranged at intervals in the radial direction, and the conveying devices 22 connected with one rotary transmission device 20 are relatively fixed, so that the material is further saved, the structural complexity is reduced, and the weight is also reduced.

Wherein, the medial assembly 110 may include: and a plurality of first radial connecting members 111, wherein the first radial connecting members 111 are extended in a radial direction, and have inner ends for connecting the rotating shaft 21 and outer ends for connecting the conveying device 22. The inner side assembly 110 is disposed near the rotating shaft 21 of the rotation transferring device 20, i.e., near the inner side of the integrated device, and is mainly used for connecting the rotating shaft 21 and the conveying device 22, so that the conveying device 22 can stably rotate around the rotating shaft 21. The first radial connecting members 111 may be channel steel structures, and the number thereof may be the same as or less than the number of the conveying devices 22, as described above. The inner end of the first radial connecting member 111 may be provided with a connecting structure, such as a bolt hole, etc., to be connected to the rotation shaft 21 through a bearing assembly. The outer end of the first radial connecting member 111 may be fixedly connected to the inner end surface of the conveying device 22 or the lower side surface of the inner end, so as to avoid affecting the task of receiving and conveying goods on the upper side of the conveying device 22.

In some embodiments, medial assembly 110 may further include: one or more first circumferential connecting members 112, the first circumferential connecting members 112 extending in the circumferential direction, connecting the plurality of first radial connecting members 111, and connecting the plurality of conveyor devices 22 extending in the radial direction, respectively. In this embodiment, the inner assembly 110 further includes a first circumferential connecting member 112, and the first circumferential connecting member 112 may be a steel plate structure. In some embodiments, the first circumferential connection member 112 may be a straight plate extending linearly, connecting adjacent ones of the first radial connection members 111; in other embodiments, the first circumferential connecting member 112 may also have an arc shape, the center of which is the axis of the rotation shaft 21, so as to reduce the torque required for rotation when performing the rotating motion. The adjacent first radial connecting parts 111 can be more stable through the first circumferential connecting part 112, and at the same time, the conveying device 22 can be connected to the lower side of one end of the rotating shaft 21, so that the conveying device 22 can also be fixed at the inner end relative position, and is stable in the rotating motion process and convenient for transmission. Meanwhile, the plurality of inner modules 110 can be conveniently connected by providing the first circumferential connecting member 112, for example, as shown in fig. 4, the adjacent inner modules 110 are connected by the first circumferential connecting member 112 of the inner module 110, so that the outer sides of the inner modules and the adjacent inner modules are stably and fixedly connected.

The outer assembly 120 is disposed at a position close to the outer side in the radial direction, and is not directly connected to the inner assembly 110, so that the installation difficulty caused by actual deviation is reduced, the material cost is reduced, and the installation is more flexible.

The inner assembly 110 is located at the inner side and mainly used for connecting the rotation shaft 21 and the conveying devices 22, and the outer assembly 120 is located at the outer side and mainly used for connecting the circumferentially adjacent conveying devices 22, so that the position relationship between the conveying devices 22 is kept stable, and since the moment at the outer side is larger away from the rotation center, stable support in the circumferential direction is more needed to ensure the reliability of the rotation transmission device 20 during the rotation process.

Lateral assembly 120 may include: a plurality of circumferential connecting members, which extend in the circumferential direction, for connecting a plurality of conveying devices 22. The circumferential connecting member can be a steel plate extending linearly, and is easy to manufacture; the arc-shaped rotary shaft can also be in an arc shape, the center of the arc-shaped circle is the axis of the rotary shaft 21, and the torsion moment in the rotary process can be reduced through the circumferential connecting components arranged in the arc shape.

In an embodiment, the circumferential connection member of the outboard assembly 120 may include: a second circumferential connection member 121 and a third circumferential connection member 122; wherein the third circumferential connection member 122 is provided radially outward of the second circumferential connection member 121. Since the radial dimension of the conveying devices 22 may be large, and may extend several meters long in practical applications, the circumferential connecting members are arranged in a staggered manner at a plurality of radial positions, that is, some circumferential connecting members are farther away from the rotation center than other circumferential connecting members, so that adjacent conveying devices 22 can be connected more stably, and the conveying devices 22 can be connected more stably with each other. More circumferential connecting parts with different radial positions can be arranged according to the actual size and rigidity requirements.

The second and third circumferential connecting members 121 and 122 may be formed of a steel plate, may be formed of a straight plate, and may have an arc shape, and may be disposed in parallel or connected to each other. In one embodiment, the third circumferential connecting member 122 may be connected to the outer edge of the transportation device 22 such that the transportation device 22 is connected to each other at a position farthest from the center of rotation, thereby making the connection more stable.

In one embodiment, there is a gap between circumferentially adjacent second circumferential connection members 121; or, a gap exists between the circumferentially adjacent third circumferential connecting members 122. In another embodiment, there is a gap between circumferentially adjacent second circumferential connection members 121 and a gap between circumferentially adjacent third circumferential connection members 122. In the above embodiment, the gap between the second circumferential connecting members 121 and the gap between the third circumferential connecting members 122 can offset the processing and assembling deviation of the large-diameter equipment, and the gap itself can offset the pressing between the circumferentially adjacent conveying devices 22 due to insufficient rigidity and circumferential deformation when the equipment rotates to form the rotational inertia.

In an embodiment, lateral assembly 120 may further include: one or more second radial connecting members 123, the second radial connecting members 123 being arranged to extend radially, with an inner end connected to the second circumferential connecting member 121 and an outer end connected to the third circumferential connecting member 122. In this embodiment, the second radial connecting member 123 connects the second circumferential connecting member 121 and the third circumferential connecting member 122, so that the connection between the members is more stable, and at the same time, the second radial connecting member 123 may be disposed at the lower side of the conveying device 22, so that the connection between the connecting assembly 100 and the conveying device 22 can be enhanced. Meanwhile, as shown in fig. 4, a plurality of outer assemblies 120 can be conveniently connected by providing the second radial connecting member 123.

In an embodiment, the third circumferential connection member 122 is arranged offset in the circumferential direction from the second circumferential connection member 121. The third circumferential connecting member 122 and the second circumferential connecting member 121 which are arranged in a staggered manner in the circumferential direction can be used to conveniently connect the outer module 120 to another outer module 120 as a unit.

In an embodiment, the first circumferential connection member 112 and the third circumferential connection member 122 are arranged in circumferential direction center alignment. In this embodiment, the first circumferential connecting member 112 and the third circumferential connecting member 122 in the connecting assembly 100 as a unit may be aligned with each other in the circumferential direction, so that the connecting assembly 100 as a unit as a whole can be conveniently combined by a plurality of units to form a structure capable of connecting a complete circumference.
