[0018] Example 1

[0019] like Figures 1-3 As shown, the cake paper tray supply device proposed in this embodiment includes a frame 1, a slide table 2, a feeding box 4, and a pneumatic feeding device.

[0020] The slide table 2 is slidably mounted on the frame 1. A limit groove is provided at the upper end of the slide table 2. A first servo cylinder 15 for driving the slide table 2 to move is installed on the frame 1. The feeding box 4 is located on one side above the frame 1. A bracket 3 is provided on the frame 1. The feeding box 4 is slidably mounted on the bracket 3. A second servo cylinder 17 for driving the feeding box 4 to move is installed on the bracket 3. The feeding box 4 has multiple feeding holes 401. A push plate 18 is slidably mounted inside the feeding hole 401. A power component for driving the multiple push plates 18 to move synchronously is installed on the feeding box 4. The power component includes a second servo motor 20 and a threaded rod 21. The second servo motor 20 is mounted on the feeding box 4. The threaded rod 21 is connected to the output shaft of the second servo motor 20. A sliding frame 19 is slidably mounted on the feeding box 4. The sliding frame 19 is threadedly connected to the threaded rod 21. A slider is connected between the sliding frame 19 and the multiple push plates 18. The feeding box 4 has multiple sliding holes for the slider to slide.

[0021] The pneumatic feeding device includes a main pipe 6, a first servo motor 10, an air pump 14, and multiple adsorption components. Two mounting bases 5 are provided on the frame 1. Hollow rotating tubes 61 are connected to both ends of the main pipe 6. The two hollow rotating tubes 61 are rotatably mounted on the mounting bases 5 on both sides. The first servo motor 10 is mounted on the mounting base 5, and its output shaft is connected to the hollow rotating tubes 61. The outer end of the hollow rotating tube 61 adjacent to the first servo motor 10 is a closed structure, while the end of the hollow rotating tube 61 on the other side is equipped with a rotary joint 13. The air pump 14... 4. Installed on the frame 1, the air pump 14 is connected to the rotary joint 13 by an air pipe. Multiple adsorption components are distributed in a ring array around the main pipe 6. The adsorption components include branch pipes 7, multiple suction pipes 8 and multiple suction cups 9. A connecting pipe 11 connects the branch pipes 7 and the main pipe 6. The branch pipes 7 and the main pipe 6 are fixedly connected. A solenoid valve 12 is installed on the connecting pipe 11. Multiple suction pipes 8 are connected to the branch pipes 7. Multiple suction cups 9 are respectively installed at the ends of multiple suction pipes 8. Multiple discharge holes 401 are set one-to-one with multiple suction cups 9 on the adsorption components.

[0022] Mounting bracket 23 is connected to mounting base 5, and infrared ranging sensor 24 is mounted on mounting bracket 23.

[0023] A silicone plate 22 is installed on the upper inner side of each of the multiple feeding holes 401. The silicone plate 22 has anti-slip texture. The anti-slip texture of the silicone plate 22 increases the friction between the paper tray and the silicone plate, preventing multiple sheets from being simultaneously adsorbed due to static electricity adhesion when stacking paper trays.

[0024] Furthermore, a microcontroller and a battery are installed on the main pipeline 6. The battery powers the microcontroller and the solenoid valve 12. The microcontroller is equipped with wireless communication capabilities and is electrically connected to multiple solenoid valves 12. A PLC controller 16 is also installed on the frame 1. The PLC controller 16 is equipped with wireless communication capabilities and is wirelessly connected to the microcontroller. The PLC controller 16 is also electrically connected to the air pump 14, the second servo motor 20, the infrared ranging sensor 24, the first servo motor 10, the second servo cylinder 17, and the first servo cylinder 15.

[0025] The following is a detailed explanation of the working principle of this technical solution:

[0026] Preliminary preparation stage: Stack multi-layer cake paper cups into multiple feeding holes 401 of feeding box 4, ensuring that the number of paper cups in each hole is the same; place the tray that receives the paper cups into the limiting groove of slide table 2, and fix the position of the tray through the limiting groove.

[0027] Paper tray adsorption and transfer: The first servo motor 10 drives the main pipe 6 to rotate, so that the suction cups 9 of a set of adsorption components are precisely aligned with the discharge hole 401 of the discharge box 4. The second servo cylinder 17 pushes the discharge box 4 to move along the bracket 3 towards the adsorption components until all suction cups 9 are in contact with the inner wall of the paper tray. The air pump 14 starts and establishes negative pressure in sequence through the air pipe, rotary joint 13, hollow rotating pipe 61 and main pipe 6. The solenoid valve 12 of the target adsorption component is opened, and the negative pressure is transmitted to the branch pipe 7, suction pipe 8 and suction cups 9 through the connecting pipe 11 until the outermost paper tray is adsorbed. It is worth noting that the solenoid valves 12 of other adsorption components are kept closed to ensure that the negative pressure is concentrated on the target station. After adsorption is completed, the second servo cylinder 17 drives the discharge box 4 to return to its original position, and the adsorbed paper tray is removed from the discharge hole 401 along with the adsorption components.

[0028] Paper tray position detection: The infrared distance sensor 24 detects the distance between itself and the outermost paper tray inside the feeding hole 401 in real time and feeds the data back to the PLC controller 16. When the paper tray is consumed and the overall stacking distance is insufficient, the PLC controller 16 starts the second servo motor 20 to drive the threaded rod 21 to rotate. The threaded rod drives the sliding frame 19 to move, and through the slider, all push plates 18 are pushed outward in sync. The push plates 18 push the stacked paper trays outward to ensure that the outermost paper tray always maintains the set distance from the infrared distance sensor 24, ensuring the reliability of the next adsorption.

[0029] Paper tray released to tray: The first servo motor 10 drives the main pipe 6 to rotate, so that the component that adsorbs the paper tray rotates to the release position directly above the slide table 2; the solenoid valve 12 of the target adsorption component closes, cutting off the negative pressure passage, the suction cup 9 loses its adsorption force, and the paper tray falls vertically into the corresponding limiting hole of the tray on the slide table 2 under the action of gravity.

[0030] Slide table transfer operation: When the current workstation of the tray is full of paper trays, the first servo cylinder 15 drives the slide table 2 to move, waiting for the next paper tray to be released; the ring array design of multiple adsorption components realizes continuous cycle operation, and with the movable slide table 2, the work efficiency is greatly improved.

[0031] Example 2

[0032] like Figure 4As shown, the cake tray supply device proposed in this embodiment differs from Embodiment 1 in that the tray can be driven by a belt conveyor 25. The upper part of the frame 1 passes through the inner side of the belt of the belt conveyor 25. During operation, the tray is placed on the belt conveyor 25. For positioning with the belt conveyor 25, this embodiment uses a Hall sensor and multiple permanent magnets. The Hall sensor is installed on the frame 1, and the multiple permanent magnets are installed on the outer periphery of the belt conveyor 25. When the permanent magnets approach the Hall sensor, they can be detected, and the belt conveyor 25 stops moving. It is worth noting that when placing the tray, care should be taken to align the tray with the permanent magnets.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
