Description

Technical Field

[0001] This utility model relates to food cooking and processing supplies, and more particularly to a food container transfer robot suitable for conveying food in tunnels. Background Technology

[0002] There are many heating methods for cooking food containers, such as electric heating, microwave heating, gas heating, and steam heating. Existing steam heating methods involve placing the food container and broth inside the food container, then placing it in a heating space (which also serves as the output chamber). Steam inlets are installed on the walls of the heating space, allowing steam to enter and heat the entire space to cook the food. To meet the needs of selling ready-to-eat meals, those skilled in the art have attempted to design a food vending machine that integrates the storage of raw food containers with the cooking process. There are many ways for vending machines to store and dispense food, one of which is storing food containers through aisles. However, existing robotic arms cannot easily and reliably transfer food containers into the aisles when storing them through aisles. Utility Model Content

[0003] The present invention aims to provide a lunchbox transfer robot that can transfer lunchboxes into storage aisles, which is suitable for aisle transportation and solves the problem that existing robots cannot easily transfer lunchboxes into storage aisles.

[0004] The above technical problems are solved by the following technical solution: a robotic arm for transferring lunch boxes in a storage aisle, characterized by comprising a carrying tray, a pusher for pushing lunch boxes onto the carrying tray, and a pusher translation mechanism that drives the pusher to extend and retract along the lunch box unloading direction. When the pusher moves towards the end of its travel in the lunch box unloading direction, the bottom wall of the lunch box supported on the carrying tray, away from the pusher, is located outside the carrying tray. In use, the carrying tray is aligned with the lunch box unloading end of the storage aisle, and the lunch box is stored on the carrying tray. The pusher translation mechanism drives the pusher to move towards the storage aisle, pushing the lunch box into the storage aisle. This method can reliably transfer lunch boxes into the storage aisle. It is particularly effective when the aisle has a multi-layer design.

[0005] Preferably, the pusher translation mechanism includes a longitudinally extending guide rail, a sliding seat slidably connected to the guide rail, a longitudinal lead screw threadedly connected to the sliding seat, and a drive motor for rotating the longitudinal lead screw. The guide rail and the drive motor are both fixed relative to the carrying tray, the longitudinal lead screw is rotatably connected to the carrying tray, and the sliding seat is connected to the pusher. This provides a specific technical solution for the pusher translation mechanism.

[0006] Preferably, the pallet has a longitudinally extending elongated clearance groove, the guide rail is located below the pallet, the sliding seat is suspended on the guide rail, the pusher is connected to one end of the connecting arm, and the other end of the connecting arm passes through the clearance groove and connects to the sliding seat. The pusher is located on the side of the sliding seat facing the direction of food container feeding. This design features a compact structure, and the guide rail, lead screw, etc., are less prone to dust accumulation.

[0007] Preferably, the drive motor is connected to the upper surface of the cargo tray, providing reliable support.

[0008] Preferably, a lower connecting plate is connected to the lower surface of the carrying tray, the longitudinal lead screw is rotatably connected to the lower connecting plate, an upper connecting plate is connected to the upper surface of the carrying tray, and the drive motor is connected to the upper connecting plate. The components are compact and easy to manufacture.

[0009] Preferably, the longitudinal lead screw is equipped with a driven synchronous pulley, and the power output shaft of the drive motor is equipped with a driving synchronous pulley. The driving synchronous pulley is connected to the driven synchronous pulley via a synchronous belt. This ensures good reliability during drive.

[0010] Preferably, the drive motor is a servo motor, which is capable of precise driving.

[0011] Preferably, the food container is fed longitudinally, and the pusher includes a transverse push plate and two inclined baffles, each connected to a corresponding transverse end of the transverse push plate, with their free ends inclined towards the food container feeding direction. This avoids lateral shifting when pushing the food container, which could prevent it from being reliably pushed into the food container aisle.

[0012] The utility model has the following beneficial effects: it can reliably transfer lunch boxes into storage aisles. Attached Figure Description
