For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0027] This embodiment describes a ring-shaped rotating platform for transporting required items to a designated location.

[0028] like Figure 1 As shown, the annular rotating platform includes a base plate 1, a drive mechanism 2, a moving base plate 3, a moving support 4, a position detection mechanism 5, and a secondary positioning mechanism 6. The drive mechanism 2, the position detection mechanism 5, and the secondary positioning mechanism 6 are each connected to a controller. The controller controls the drive mechanism 2 and the secondary positioning mechanism 6 according to the detection signal from the position detection mechanism 5, so that the moving base plate 3 stops accurately at a preset position.

[0029] Drive mechanism 2 is mounted in the middle of base plate 1 and provides the driving force for the annular rotating platform. In this embodiment, drive mechanism 2 comprises a driving wheel, a driven wheel, and an annular chain track. The driving wheel and the driven wheel are spaced apart and mounted in the middle of base plate 1. The annular chain track is sleeved over the driving wheel and the driven wheel. Driven by the driving wheel, the annular chain track rotates around the driving wheel and the driven wheel.

[0030] The annular chain track is composed of a plurality of chain links. A plurality of moving base plates 3 are arranged at intervals around the annular chain track, the middle of one end of the bottom of the moving base plate 3 is connected to the chain link, and a moving support 4 is installed at the other end of the bottom of the moving base plate 3. The moving support 4 supports the moving base plate 3 and can move freely, so that the moving base plate 3 can rotate along the annular chain track under the drive of the annular chain track, and the moving base plate 3 is used to bear the load. The moving base plate 3 of this embodiment is connected to a chain link, which can ensure that the moving base plate 3 can realize circular motion in the circular part of the annular chain track. Preferably, the moving support 4 of this embodiment is a rotating structure such as a universal ball, a universal wheel or a bull's eye bearing. Compared with the existing annular rotating platform that uses an annular guide rail to support the moving base plate 3, the moving support 4 of this embodiment can meet the annular rotation requirement of the moving base plate 3 and reduce the cost.

[0031] At the preset workstation, the position detection mechanism 5 and the secondary positioning mechanism 6 are installed in sequence at preset positions on the base plate 1 along the movement direction of the moving base plate 3. For example, the position detection mechanism 5 is installed on the inner side of the annular chain rail, and the secondary positioning mechanism 6 is installed on the outer side of the annular chain rail, and the distance between the position detection mechanism 5 and the annular chain rail is smaller than the distance between the annular chain rail and the moving support 4.

[0032] The position detection mechanism 5 is used to collect the arrival signal when the moving base plate 3 moves to the preset position, and feed the arrival signal back to the controller. The controller controls the driving mechanism 2 to stop the movement according to the arrival signal of the moving base plate 3. The position detection mechanism 5 of this embodiment can adopt a displacement sensor such as a photoelectric sensor or a Hall sensor.

[0033] The secondary positioning mechanism 6 is used to prevent the moving base plate 3 from further movement, thereby increasing the accuracy of the moving base plate 3's stopping position. In this embodiment, the secondary positioning mechanism 6 comprises a power unit and a positioning plate. The output end of the power unit is connected to the positioning plate. The power unit drives the positioning plate to extend and retract. When the positioning plate extends, it engages the moving base plate 3, preventing it from further movement. When the positioning plate retracts, it does not affect the movement of the moving base plate 3. The power unit can be a motor or a pneumatic cylinder, for example.

[0034] A pallet is also provided on the moving base plate 3 for placing items to be transported.

[0035] The operation of the annular rotating platform of this embodiment is described by taking the annular rotating platform of this embodiment installed on the cartoning station of the automatic cartoning machine for glass bottles to transport cartons as an example. The position detection mechanism 5 and the secondary positioning mechanism 6 are respectively set on the cartoning station.

[0036] like Figure 2As shown, a carton support plate 7 for supporting a carton is installed on the moving base plate 3. The carton is placed on the carton support plate 7. When the carton on the box loading station is filled with glass bottles, the driving mechanism 2 is started, driving multiple moving base plates 3 to move synchronously. The carton filled with glass bottles moves to the output position for output. When the next empty carton adjacent to it enters the box loading station, the position detection mechanism 5 detects the arrival signal of the next moving base plate 3 and feeds the arrival signal back to the controller. The controller controls the driving mechanism 2 to stop according to the arrival signal, and then the ring chain track drives the moving base plate 3 to stop moving. At the same time, the controller controls the secondary positioning mechanism 6 to start according to the arrival signal. The power device drives the positioning plate to extend and clamp the moving base plate 3 on the box loading station to prevent the moving base plate 3 from moving out of the box loading station, ensuring that the empty carton stops at the box loading station and waits for the box loading operation. After the carton on the box loading station is full, the driving mechanism 2 is started again to repeat the above process and carry out the box loading operation.

[0037] Although the principles of the present invention have been described in detail above in conjunction with the preferred embodiments of the present invention, those skilled in the art should understand that the above embodiments are merely illustrative of the implementation of the present invention and are not intended to limit the scope of the present invention. The details in the embodiments do not constitute a limitation on the scope of the present invention. Without departing from the spirit and scope of the present invention, any obvious changes such as equivalent transformations and simple substitutions based on the technical solutions of the present invention fall within the scope of protection of the present invention.
