As shown in fig. 1 and 2, a swiveling device for transporting a pallet according to an embodiment of the present invention includes a swiveling unit. The slewing unit comprises a turntable 1. The rotary table 1 is obliquely arranged, and the rotary table 1 inclines outwards from top to bottom. The outward inclination is an inclination toward a direction deviating from the track. In use, the turning device is mounted on a track 2 comprising an upper channel 201 and a lower channel 202.

The turning device of the above embodiment is used for a rail 2 having an upper groove 201 and a lower groove 202. The tray 6 moves with the conveyor in the upper run 201 and the lower run 202. The turntable 1 is arranged, so that the tray 6 can still move smoothly after being turned. The tray 6 comprises a base and a support rod fixedly connected to the base. When the tray 6 moves in the upper channel 201, the struts are located above the base. The bar is located below the base when the tray 6 moves in the lower channel 202. The rotary table 1 is obliquely arranged, and the rotary table 1 inclines outwards from top to bottom. The distance between the upper end of the turntable 1 and the track is smaller than the distance between the lower end of the turntable 1 and the track. The distance between the lower end of the turntable 1 and the track is large, providing a space for changing the positional relationship between the tray 6 and the conveyor, so that the tray 6 can be smoothly moved in both the upper groove 201 and the lower groove 202.

Preferably, the rotating device further comprises a power source 3, and the power source 3 is connected with the rotating disc 1 to drive the rotating disc 1 to rotate. The power source 3 may be a direct power device or an indirect power device. The direct power device is a device for directly providing power for the turntable 1, such as a cylinder, an electric cylinder, a motor, and the like. The indirect power device is connected with the rotating disc 1 of the embodiment through a transmission device by means of other power sources on the equipment, so that the rotating disc 1 rotates. Whether direct or indirect, as long as power is provided to rotate the turntable 1.

Preferably, the turning unit further comprises a guide 4, the guide 4 being connected to the track 2 or the turning device for guiding the conveyor belt 5. The rotary table 1 is obliquely arranged, and the rotary table 1 inclines outwards from top to bottom. The lower end of the turntable 1 is offset from the track. The conveyor at the lower end of the turntable 1 is also offset from the track. Therefore, the guide 4 is provided to return the conveying device located at the lower end of the turntable 1 into the lower groove 202, so that the conveying device located in the lower groove 202 can perform the conveying of the tray 6.

The guide 4 may have various structures as long as it can guide the conveyor belt 5. In the present embodiment, the following structures are preferable.

First preferred structure: as shown in fig. 3, the guide 4 is a guide body 402 including a guide groove 401. The guide slot 401 has one end opposite to the bottom of the turntable 1 and the other end opposite to the lower slot 202 of the track. In the structure, the conveyer belt 5 is sleeved on the turntable 1. The conveyor belt 5 enters the guide groove 401 from the lower end of the turntable 1, moves in the guide groove 401, and enters the lower groove 202. By means of the guide 4, it is achieved that the conveyor belt 5 enters the lower run channel 202 from the lower end of the turntable 1. The tray 6 is located in the lower groove 202. In this way, the conveyor belt 5 can effect the transport of the trays 6.

Second preferred structure: in consideration of the first preferred structure, the conveyor belt 5 may be in contact with the wall surface of the guide groove 401 to rub against the wall surface, and the conveyor belt 5 may be damaged, and therefore, in addition to the first preferred structure, as shown in fig. 4, the side wall of the guide groove 401 is provided with the balls 406. Thus, the conveyor belt 5 moves in the guide groove 401, and comes into contact with the balls 406. Rolling friction is adopted between the two, so that the friction resistance is reduced, and the transportation of the tray 6 is facilitated.

The third preferred structure: the guide 4 comprises a base 403 and a roller 404 arranged on the base 403. In use, the conveyor passes from the bottom of the carousel 1 around the rollers 404 and into the chute 202. The frictional resistance is reduced due to the rolling friction of the conveyor and the rollers 404. More preferably, as shown in fig. 5, there are at least two rollers 404, and a conveying passage 405 is formed between the rollers 404; the conveying channel 405 is opposite to the bottom of the turntable 1 at one end and opposite to the lower groove 202 of the track at the other end. In this preferred structure, the conveyor belt 5 enters the conveying path 405 from the lower end of the turntable 1, moves in the conveying path 405, and enters the lower groove 202. By means of the guide 4, it is achieved that the conveyor belt 5 enters the lower run channel 202 from the lower end of the turntable 1. The tray 6 is located in the lower groove 202. In this way, the conveyor belt 5 can effect the transport of the trays 6. Meanwhile, in the preferred embodiment, the conveyor belt 5 contacts the rollers 404 while moving in the conveying path 405. The conveyer belt 5 is in rolling friction with the rollers 404, so that the friction force during the movement is reduced.

The guide 4 effects a movement of the conveyor belt 5 from below the turntable 1 into the lower run channel 202. The guide 4 has various structures. The three embodiments described above are merely preferred exemplary constructions. When setting up 4 carousels, guide 4 contracts carousel lower extreme's conveyer belt 5 for the interval of two conveyer belts 5 is slightly littleer than the external diameter on tray 6 chassis, in order to guarantee that tray 6 completely depends on and the 5 upper ends of conveyer belt, leans on friction drive to remove.

As a preferable example, there are two revolving units, and the two revolving units are located at two ends of the track 2 on the same side. Two rotary units are arranged at two ends of the same side of the track 2. The conveyor belt 5 is sleeved on the two rotary units. A conveyor belt 5 may carry the trays 6.

Preferably, the number of the turning units is four, and the four turning units are located at two ends of the rail 2. Four rotary units are arranged at two ends of the two sides of the track 2. The conveyor belt 5 is sleeved on the two rotary units positioned on the same side of the track 2. Two conveyor belts 5 effect the transport of the trays 6. The use of two conveyor belts 5 to transport the pallet 6 is more stable and efficient than the use of one conveyor belt 5 to transport the pallet 6. Preferably, two rotating discs 1 which are opposite to each other and located on two sides of the track 2 in the four rotating units are arranged in a splayed shape.

When four rotation units are provided, the distance between the upper ends of two opposite rotating discs 1 is smaller than the distance between the lower ends of the rotating discs 1. This solves the problem of access to the tray 6. The structure of narrow top and wide bottom is adopted, the narrow top means that the distance between two conveyer belts 5 sleeved on the turntable 1 is smaller than the diameter of the base of the tray 6, so that the tray 6 on the upper layer can fall on the conveyer belts 5 completely. The lower width means that the distance between the two conveyor belts 5 is larger than the diameter of the base of the tray 6, so that the tray 6 on the lower layer can pass through the two conveyor belts 5 and enter the subsequent track in a transition manner.

When four rotary units are arranged, preferably, the rotating shafts of the two opposite rotating discs 1 positioned at two sides of the track 2 are connected to realize synchronous rotation. The rotating shafts of the two rotating discs 1 are connected and can be connected by a coupler, a flexible shaft or a bevel gear. This eliminates the need for providing a plurality of power sources 3. When the rotating shafts of the two rotating discs 1 are connected, as long as one of the rotating discs 1 rotates, the other rotating disc 1 also rotates synchronously. In the four rotary tables 1 of this embodiment, if one rotary table 1 is connected to the power source 3, the other rotary tables 1 are connected to each other via the conveyor belt 5 or the rotary shaft and rotate together with the same. This simplifies the equipment and improves the synchronization.

The swing mechanisms of the present embodiment are disposed on both sides of the vertical track to drive the conveyor belt 5 to rotate, and the narrow-top and wide-bottom characteristics of the swing mechanisms are utilized to facilitate the smooth transportation of the trays 6 through the conveyor belt 5 in the lower chute 202.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to further illustrate the principles of the invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention, which is also intended to be covered by the appended claims.
