Description

Technical Field

[0001] This utility model relates to the field of rotational molding production equipment, and in particular to a conveying device for rotational molding production line production. Background Technology

[0002] Some rotationally molded parts are quite large, such as large rotationally molded oil tanks, which need to be removed by a robotic arm after mold opening. To avoid the accumulation of rotationally molded oil tanks, a conveyor device is also needed to transport them to the next process for further processing, such as inspection and labeling.

[0003] In the prior art, the conveying of rotational molding parts or other materials usually relies solely on conveyor belts. For example, patent CN108502461A discloses a rotational molding machine conveying device for assembly line production, which uses a conveyor belt for conveying. The rotational molding parts cannot be positioned on the conveyor belt, which is not conducive to the subsequent gripping of the rotational molding parts by the robot arm and is difficult to adapt to assembly line production, so improvements are needed. Utility Model Content

The stops are disposed on the top of the sliders and extend upward to above the positioning trays. The positioning trays are provided with fastening screws that extend downward into the grooves and are connected to the sliders.

[0007] The groove is a T-shaped groove.

[0008] The top inner side of the stop block is provided with a downwardly extending inclined surface.

[0009] The slider is provided with threaded holes corresponding to the fastening screws.

[0010] The conveyor frame is equipped with rollers that support the operation of the conveyor belt.

[0011] The conveyor frame is equipped with a motor that drives one of the rollers to rotate.

[0012] The conveyor frame is equipped with a controller for controlling the rotation of the motor.

[0013] The conveyor frame is equipped with a bracket located on one side of the conveyor belt. The bracket is equipped with a first photoelectric sensor pointing to the positioning tray. The rotomolded part is placed on the positioning tray. The bracket is equipped with a second photoelectric sensor pointing to the rotomolded part. The first and second photoelectric sensors are respectively connected to the controller to send signals.

[0014] The beneficial effects of this utility model are as follows: A conveying device for rotational molding production line conveys rotational molded parts through a positioning pallet and uses stops to position the rotational molded parts in multiple directions, avoiding relative movement of the rotational molded parts on the positioning pallet, improving the positional accuracy of the conveying process, facilitating the loading and unloading of rotational molded parts by robotic arms, and improving the adaptability to rotational molding production line production.

[0018] like Figure 1 and Figure 2 The conveying device shown is used for positioning and conveying rotationally molded parts 7 in a production line. It includes a conveyor frame 1, a positioning tray 3, a slider, and a stop. The conveyor frame 1 is equipped with a horizontally running conveyor belt 2. The positioning trays 3 are spaced apart on the conveyor belt 2 and can be fixed with screws so that the positioning trays 3 can switch positions as the conveyor belt 2 moves.

[0019] A roller 6 is provided on the conveyor frame 1 to support the operation of the conveyor belt 2. In this embodiment, a motor 4 is provided on the conveyor frame 1 to drive one of the rollers 6 to rotate. A controller 5 is provided on the conveyor frame 1 to control the rotation of the motor 4. The controller 5 can be a PLC to control the intermittent rotation of the motor 4 and realize the intermittent displacement of the positioning tray 3 to adapt to the production rhythm of the rotational molding production line.

[0020] The rotationally molded part 7 is placed on the positioning tray 3 and can be picked up and placed by a robotic arm on the assembly line. To achieve the positioning of the rotationally molded part 7, such as... Figure 2As shown, the outer circle of the positioning tray 3 is provided with grooves 12 extending radially therefrom at intervals. The slider 8 is slidably disposed in the grooves 12. In this embodiment, the grooves 12 are T-shaped grooves, and four grooves 12 are arranged in a circular array on the outer circle of the positioning tray 3.
