[0027] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0028] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0029] As society progresses, people are demanding higher and higher standards of living. Besides regular exercise, people consume plenty of fruits and vegetables to prevent vitamin and other nutrient deficiencies. They also have specific requirements regarding the freshness of fruit. With technological advancements and societal progress, fruit sorting equipment is increasingly automated. However, current automated fruit sorting equipment often experiences issues where two fruit crates are fed into the turning machine too close together, interfering with its operation. When this interference occurs, the turning machine stops but does not issue an alarm. After the crates are separated, the fruit is transported in piles, hindering subsequent processing. The equipment is also prone to motor jamming.
[0030] Based on this, please refer to Figure 1 The automatic fruit unloading system 1000 provided in the embodiments of this utility model can effectively improve the aforementioned technical problems. This automatic fruit unloading system 1000 can orderly separate the fruit from the fruit basket, completing the automatic fruit unloading process.
[0031] Figure 1 This is a schematic diagram of the automatic fruit unloading system provided in an embodiment of this utility model, as shown below. Figure 1As shown, the automatic fruit unloading system 1000 provided in this embodiment includes a fruit frame flipping device 100, an empty frame flipping device 200, a fruit conveying device 300, and a control device. The fruit frame flipping device 100 is connected to both the empty frame flipping device 200 and the fruit conveying device 300. All three devices are electrically connected to the control device. The control device controls the operation of the fruit frame flipping device 100, the empty frame flipping device 200, and the fruit conveying device 300 to achieve separation of the fruit from the fruit frame and automatic unloading. The control device can simultaneously control the fruit frame flipping device 100, the empty frame flipping device 200, and the fruit conveying device 300. Alternatively, the control device can control the operation of each device separately according to specific circumstances, thereby orderly separating the fruit from the fruit frame and completing the automatic unloading process.
[0032] To reduce manual intervention and achieve a high degree of automation in the automatic fruit unloading system 1000, thereby improving unloading efficiency, the automatic fruit unloading system 1000 in this embodiment also includes a feeding device 400. The feeding device 400 is connected to the fruit frame flipping device 100 and is used to transport fruit frames containing fruit to the fruit frame flipping device 100. The feeding device 400 can automatically feed fruit and transport the fruit frames containing fruit to the position of the fruit frame flipping device 100 for unloading.
[0033] To facilitate subsequent actions of the device based on the position of the fruit-filled crate, a fifth detector is provided at one end of the feeding device 400 near the fruit crate flipping device 100 in this embodiment. The fifth detector is electrically connected to the control device. The fifth detector determines whether the fruit crate is in position and sends a feedback signal to the control device, which then controls the feeding device 400 to operate based on the received signal. When the fifth detector detects that the fruit crate has passed the end of the feeding device 400 and reached the fruit crate flipping device 100, the control device receives the signal from the fifth detector and controls the fruit crate flipping device 100 to flip. When the fifth detector does not detect the fruit crate passing by, the control device continues to control the feeding device 400 to transport the fruit crate until the fruit crate passes the end of the feeding device 400. The fifth detector can be a position sensor, photoelectric sensor, or other sensing device, and is not limited here.
[0034] Furthermore, because the fruit frame flipping device 100 may not return to its initial shape after flipping the previous fruit frame, it may be unable to receive fruit frames containing fruit. In this embodiment, a fourth detector is provided at the fruit frame flipping device 100, which is electrically connected to the control device. The fourth detector is used to determine whether the fruit frame flipping device 100 is in a position where it can receive fruit frames, and it sends a feedback signal to the control device. The control device then controls the fruit frame flipping device 100 to operate based on the received signal. By setting the fourth detector, the shape of the fruit frame flipping device 100 can be detected to determine whether it can receive the next fruit frame containing fruit for flipping. When the fourth detector detects that the fruit frame flipping device 100 is in a state parallel to the feeding device 400, it can receive fruit frames, and the control device controls the feeding device 400 to transport the fruit frame containing fruit to the fruit frame flipping device 100. When the fourth detector detects that the fruit frame flipping device 100 cannot receive fruit frames, the control device controls the fruit frame flipping device 100 to rotate back to its initial shape to receive fruit frames. In this embodiment, the fourth detector is a visual detection device, such as a camera, but it can also be other detection structures, which are not limited here.
[0035] To accurately determine the position of the fruit-filled crate at the fruit-crane flipping device 100, the automatic fruit unloading system in this embodiment further includes a first detection device. The first detection device is mounted on the fruit-crane flipping device 100 and is electrically connected to the control device. The first detection device detects whether the fruit crate has reached the designated position. After detecting that the fruit crate has reached the designated position, the first detection device sends a signal to the control device. The control device then controls the fruit-crane flipping device 100 to clamp the fruit crate and flip it, changing the opening direction of the crate and thus separating the fruit from the crate. When the first detection device detects that the fruit-filled crate has not reached the designated position of the fruit-crane flipping device 100, the control device then controls the feeding device 400 to convey the fruit and controls the fruit-crane flipping device 100 to remain stationary. The first detection device can be a position sensor, photoelectric sensor, or other sensing element, and is not limited thereto.
[0036] Furthermore, the fruit frame flipping device 100 in this embodiment is also equipped with a second detection device. The second detection device is electrically connected to the control device. The second detection device is used to detect whether the fruit frame flipping device 100 clamps the fruit frame and feeds back a signal to the control device. The control device controls the fruit frame flipping device 100 to perform a flipping action based on the feedback signal. By setting the second detection device, it can be determined whether the fruit frame flipping device 100 clamps the fruit frame containing the fruit. If it is not clamped, the control device receives the signal and controls the fruit frame flipping device 100 to continue the clamping action; if it is clamped, the control device receives the signal and controls the fruit frame flipping device 100 to perform a flipping action to separate the fruit from the fruit frame. The second detection device can be a photoelectric sensor, other sensors, or other structures, which are not limited here.
[0037] After the fruit is separated from the fruit crate, it is conveyed and boxed by the fruit conveying device 300. To prevent the fruit from piling up during conveying and continuing to convey even when the box is full, a third detector is installed at the end of the fruit conveying device 300 away from the fruit crate flipping device 100 in this embodiment. The third detector is electrically connected to the control device. The third detector is used to determine whether the fruit is full and sends a feedback signal to the control device, which then controls whether the fruit crate flipping device 100 and the fruit conveying device 300 continue to operate. When the third detector detects that the conveyed fruit has reached the full position, i.e., a box is full, the control device receives the signal and controls the feeding device 400, the fruit crate flipping device 100, and the fruit conveying device 300 to stop working, so as to achieve orderly unloading of fruit and prevent stacking or jamming, which would affect the normal operation of the system. When the third detector detects that the conveyed fruit has reached the full position, i.e., a box is not full, the control device receives the signal and controls the feeding device 400, the fruit crate flipping device 100, and the fruit conveying device 300 to continue working.
[0038] Since the fruit and fruit are separated after the fruit frame is flipped by the fruit frame flipping device 100, the opening of the fruit frame is not facing upwards, which is inconvenient for subsequent placement or loading. Therefore, the automatic fruit unloading system 1000 in this embodiment also includes an empty frame flipping device 200, which flips empty fruit frames so that the opening faces upwards. To facilitate the correct operation of the empty frame flipping device 200 and prevent it from being flipped empty, the empty frame flipping device 200 in this embodiment is equipped with a first detector. The first detector is electrically connected to the control device. The first detector is used to detect when the fruit frame reaches the position of the empty frame flipping device 200 and feeds back a signal to the control device. The control device then controls the empty frame flipping device 200 to clamp and flip the fruit frame. When the first detector detects that the empty fruit frame has not reached the fruit frame flipping position, the control device receives the signal and controls the empty frame flipping device 200 not to operate. The first detector can be a position sensor, photoelectric sensor, or other sensing device, and is not limited here.
[0039] Empty fruit crates may over-flip and become distorted after being flipped by the fruit crate flipping device 100. Therefore, in this embodiment, the empty crate flipping device 200 is further equipped with a second detector. The second detector is electrically connected to the control device. The second detector detects whether the fruit crate meets the flipping conditions and sends a feedback signal to the control device. The control device then controls whether the empty crate flipping device 200 operates based on the feedback signal. When the second detector detects that the empty fruit crate meets the flipping conditions, the control device receives the signal and controls the empty crate flipping device 200 to perform the flipping action; when the second detector detects that the empty fruit crate does not meet the flipping conditions, the control device receives the signal and controls the empty crate flipping device 200 not to operate. The second detector can be a visual detection device, such as a camera, or other detection structures; no limitation is made here.
[0040] In addition, to facilitate the transport of empty fruit crates, the automatic fruit unloading system 1000 in this embodiment also includes an empty crate conveying device 500, which is connected to the empty crate flipping device 200. The empty crate conveying device 500 is used to transport empty fruit crates to a designated position.
[0041] The working principle of the automatic fruit unloading system 1000 provided in this embodiment is as follows:
[0042] The automatic fruit unloading system 1000 activates its automatic mode. The feeding device 400 transports fruit-filled crates to the crate-turning device 100. A fifth detector on the feeding device 400, located near the crate-turning device 100, determines if the crate is in position. Simultaneously, a fourth detector on the crate-turning device 100 determines if it is in an acceptable position. If both conditions are met, the control device receives signals from the fourth and fifth detectors and controls the feeding device 400 to transport the crate to the crate-turning device 100. Then, a first detection device on the crate-turning device 100 checks if the crate has reached its designated position. If so, the control device clamps the crate. Next, a second detection device on the crate-turning device 100 checks if it is clamped. If clamped, the controller controls the crate-turning device 100 to flip, emptying the fruit from the crate and separating it from the crate.
[0043] Fruits are conveyed and boxed by fruit conveying device 300. A third detector is installed at the end of fruit conveying device 300 away from fruit frame turning device 100. The third detector can detect whether the fruit has reached the full position. If the fruit has reached the full position, the control device controls the feeding device 400, fruit frame turning device 100 and fruit conveying device 300 to stop operating.
[0044] Empty fruit crates are conveyed to the empty fruit crate flipping device 100. A first detector on the device detects whether the empty fruit crate has reached the designated position. Simultaneously, a second detector on the device detects whether the shape of the empty fruit crate meets the flipping conditions. If the signals from both the first and second detectors meet the flipping conditions, the control device receives a signal and controls the empty crate flipping device 200 to clamp and flip the empty fruit crate, turning the opening of the empty fruit crate upwards.
[0045] In summary, the automatic fruit unloading system 1000 includes a fruit frame flipping device 100, an empty frame flipping device 200, a fruit conveying device 300, and a control device. The fruit frame flipping device 100 is connected to both the empty frame flipping device 200 and the fruit conveying device 300. All three devices are electrically connected to the control device. The control device controls the operation of the fruit frame flipping device 100, the empty frame flipping device 200, and the fruit conveying device 300 to achieve automatic fruit unloading by separating the fruit from the fruit frame. The control device can simultaneously control the fruit frame flipping device 100, the empty frame flipping device 200, and the fruit conveying device 300, or it can control each device individually according to specific circumstances, thus orderly separating the fruit from the fruit frame and completing the automatic fruit unloading process.
[0046] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
