[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described below in conjunction with specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art.

[0016] This utility model provides a food inspection device for a rotary equipment, including a rotary equipment and an inspection mechanism. The rotary equipment includes a rotary table 1 and a circumferentially rotatable transmission line 2 mounted on the rotary table 1. Several containers 8 containing food are placed at intervals along the transmission line. The inspection mechanism includes a lifting mechanism, a weighing electric gripper 3, a first proximity switch 4, a barcode 5, a barcode scanner 6, a control device 7, and a display device. The weighing electric gripper 3 is positioned above the transmission line 2 via the lifting mechanism. The first proximity switch 4 is located on one side of the transmission line 2, closer to the outlet end relative to the direction of transmission line movement. The barcode 5 is uniquely located on the side of each container 8 containing food. The barcode scanner 6 is located on one side of the transmission line 2, closer to the inlet end relative to the direction of transmission line movement, with its scanning port facing the barcode on the side of the container. The control device 7 is connected to the lifting mechanism, the weighing electric gripper 3, the first proximity switch 4, the barcode scanner 6, and the display device, and can be connected wirelessly or via wired connection, depending on the situation. If the rotating equipment extends into the food preparation area or is located near a window in the food preparation area, the detection mechanism should be placed on the transmission line located in or near the food preparation area. The display device should be placed in a suitable location in the food preparation area.

[0017] The weighing electric gripper is an existing technology product that integrates gripping and weighing. Also known as a weighing gripper or an electric gripper with weighing function, it includes a weighing device 31 and an electric gripper 32 arranged below the weighing device 31. A display screen is provided on the side of the weighing device. When the electric gripper grabs an item and lifts it to a certain height, the weight of the grabbed item is displayed on the screen. Here, the weighing electric gripper is connected to the control device via wired or wireless means to achieve two-way communication. In this embodiment, considering the diameter of the container, gripping arms 33 are respectively provided on the outer sides of the two grippers of the electric gripper 32. When open, the gripping arms 33 are located on both sides of the transmission line. The shape of the gripping arms is adapted to the shape of the container. Here, the container is rectangular, and the gripping arms are straight and adapted to it. Depending on the shape of the container, they can also be curved or other suitable structures.

[0018] The barcode scanner is also a product of existing technology. It uses a high-performance scanning head, automatically senses and scans codes as soon as they are displayed, has high sensitivity, fast scanning speed, and strong decoding capabilities. It can recognize wrinkled codes, blurred codes, and color codes, and transmits the recognized barcodes to the control device, which then reads the corresponding barcode information. The barcode information here includes the dish name and the corresponding numerical code for the dish. For example, spinach, 1-1; spinach, 1-2; beef, 2-1; beef, 2-2. The first digit of the numerical code defaults to the product name serial number, and the second digit defaults to the first product, second product, etc., used to distinguish multiple dishes of the same dish.

[0019] When using this device, the containers holding the food must be identical, and the weight difference between different types of products must be minimal. Ice can be added to vegetables to increase their weight. The sum of the container weight and 10% of the product weight is used as the standard data, and this standard data is written into the control device as the setting data. Containers holding the food are placed at intervals on the rotary table conveyor line and move with it. When the first proximity switch detects a container, it sends a signal to the control device. The container is positioned directly under the weighing electric gripper, which then moves closer together to clamp the container. The lifting mechanism then moves the weighing electric gripper up a certain distance and then down to its original position, placing the container on the conveyor line. The weighing electric gripper weighs the container during its ascent and sends the weight data to the control device. When the proximity switch detects the container, the barcode on the side of the container is exactly within the scanning area of ​​the barcode scanner. After the scanner senses and scans the barcode, it uploads the barcode to the control device, which then displays it on the display device. Because the electric gripper of the weighing device rises very little, the time interval between receiving the weighing data and the barcode is very short, which can be understood as almost simultaneous reception. The control device compares the weighing data with the set data. If the weighing data is less than the set data, it is assumed that there is only a small amount of food in the container. The control device will display the barcode information and further prompt "Please add food" with text. This text is set to be highlighted or flashing, indicating that there is very little food in the container corresponding to this barcode and it needs to be added. If the weighing data is greater than the set data, it is assumed that there is still food in the container, and no text prompt is given. Currently, after multiple tests, even when the transmission line moves at a relatively slow speed, there is basically no tilting phenomenon when picking up and placing the food.

[0020] Meanwhile, to facilitate quick retrieval of the corresponding dish, a positioning block 17 is provided on the front or back of the container 8 containing the dish. The top of the positioning block 17 is marked with a numerical code, which is written into the barcode information on the side of the container 8. In other words, the numerical code is the same as the numerical code in the barcode information. For example, the numerical code on the top of the container could be 1-1, 1-2, 2-1, or 2-2, matching the numerical code in the barcode information. By setting a numerical code on the top of the container, the corresponding container can be quickly located for dish replacement. The positioning block 17 can be integrally formed with the container and laser-printed with the numerical code, or it can be glued on later with strong adhesive, and then the numerical code is affixed and waterproofed.

[0021] In this embodiment, the lifting mechanism includes a gantry frame 9 and an electric cylinder 10. The gantry frame 9 is mounted above the transmission line 2, and the electric cylinder 10 is located on the top of the gantry frame 9. Its telescopic shaft extends through the top plate into the interior of the gantry frame. The weighing electric gripper 3 is arranged on the telescopic shaft of the electric cylinder 10 through a connector 11. The electric cylinder drives the weighing electric gripper up and down, which is relatively quiet and the position is more accurate. At the same time, the first proximity switch 4 and the barcode scanner 6 are both installed inside the side plate of the gantry frame 9 and extend into the interior of the gantry frame.

[0022] Furthermore, the gantry frame 9 is composed of an inverted T-shaped side plate 91, an L-shaped side plate 92, and a top plate 93. A support platform 14 is provided on the outer side of the rotary table 1. The T-shaped side plate 91 is detachably mounted on the support platform 14, and its bottom plate top surface is flush with the top surface of the rotary table. The L-shaped side plate 92 is detachably mounted on the inner top surface of the rotary table, and the top plate 93 is detachably mounted on the top of the inverted T-shaped side plate 91 and the L-shaped side plate 92.

[0023] To ensure the accuracy and stability of the up-and-down movement of the electric weighing gripper, T-shaped grooves 12 are provided on the upper part of the opposite surfaces of the two side plates of the gantry frame 9. Fixing members 13 are respectively provided on the top left and right sides of the electric weighing gripper 3. A T-shaped part that cooperates with the T-shaped groove is provided on the side of the fixing member 13 away from the electric weighing gripper 3.

[0024] In addition, to photograph and document the dishes for later review, a camera 15 and a second proximity switch 16 are mounted on one side of the turntable 1 via brackets. The camera 15's aperture faces downwards and is directly opposite the transmission line 2. The camera 15 is connected to the second proximity switch 16 and the control device 7. When the second proximity switch detects a dish, it sends a signal to activate the camera. At this time, the dish is directly below the camera, which takes a picture and transmits the image to the control device. The control device receives the captured image and saves it to a local memory card for easy retrieval and review later. Due to the digital coding on the top of the dish, the photographed dish and its corresponding dish are immediately apparent.

[0025] Furthermore, it is known that spoiled food will exhibit changes in appearance. For example, stale meatballs will have an excessively dark or light color, or develop spots; stale vegetables will turn yellow or rot; and stale raw meat will appear grayish-green or even develop spots. To detect spoilage, an image recognition processor can be introduced. This processor has a built-in recognition model. Using a pre-trained model, the image recognition processor can determine the quality of the food based on images captured by a camera and output the result to a control device. The control device then sends the result to a display device for notification. Since image recognition is a commonly used technology in the industry, it will not be discussed in detail here.
