[0025] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0026] See also Figure 1 In the embodiment of the present application, a turning machine 10 is provided, which can be applied to sorting equipment. Specifically, the turning machine 10 can turn over a cargo box containing fruits and vegetables to dump out the fruits and vegetables in the cargo box, so as to facilitate the fruits and vegetables to enter the subsequent sorting operation. The turning machine 10 can improve the technical problems of low efficiency of dumping fruits and vegetables in cargo boxes and easy damage to fruits and vegetables in the prior art.

[0027] In this embodiment, the flipping machine 10 includes a flipping assembly 100, a lifting device 200, an adaptive device, an input line 300 and an output line 400. The flipping assembly 100 includes a flipping drive device 110 and two conveying lines 120; the two conveying lines 120 are respectively arranged on opposite sides of the flipping drive device 110, the two conveying lines 120 are arranged in parallel, and the conveying directions of the two conveying lines 120 are opposite; the flipping drive device 110 has a first station and a second station, the first station and the second station are respectively located on opposite sides of the flipping drive device 110, and the first station is located below the second station; the flipping drive device 110 is used to drive the two conveying lines 120 to flip with the flipping drive device 110 as the center, so that the two conveying lines 120 switch positions in the first station and the second station respectively. In other words, the conveyor line 120 located at the first station is located at the second station after being flipped by the flip drive device 110, realizing the position switching of the conveyor line 120; similarly, the conveyor line 120 located at the second station is located at the first station after being flipped by the flip drive device 110, realizing the position switching of the conveyor line 120. Figure 1 Taking the two conveyor lines 120 in the figure as an example, the conveying direction of the upper conveyor line 120 (the conveyor line 120 at the second station) is to the left, while the conveying direction of the lower conveyor line 120 (the conveyor line 120 at the first station) is to the right. It is precisely because the conveying directions of the two conveyor lines 120 are opposite that after the two conveyor lines 120 are flipped, the conveying direction of the conveyor line 120 at the first station does not change (before and after the flip, the conveyor line 120 at the first station is transported to the right; similarly, the conveyor line 120 at the second station is transported to the left). Both conveyor lines 120 are provided with a lifting device 200; the lifting device 200 on the conveyor line 120 at the first station is used to lift the cargo box so that the cargo box moves closer to the conveyor line 120 at the second station. The adaptive device is arranged at the end of the conveyor line 120 at the first station, and is used to clamp the cargo box on the conveyor line 120 at the first station, and move the cargo box to the conveyor line 120 at the second station to output the empty cargo box. The input line 300 and the output line 400 are arranged at both sides of the first station, respectively. The input line 300 is used to input the cargo box containing fruits and vegetables to the conveyor line 120 at the first station; the output line 400 is used to receive the fruits and vegetables outputted by the conveyor line 120 at the first station and output the fruits and vegetables.

[0028] Optionally, in this embodiment, the preset position can be the middle position of the conveyor line 120 located at the first workstation. Based on this, the position of the jacking device 200 does not change before and after the flipping is completed, so that the jacking device 200 can continue to lift the cargo box without changing its position.

[0029] In addition, precisely because the two conveyor lines 120 are arranged in parallel, when the conveyor line 120 located at the first station conveys the cargo box along the horizontal line, the cargo box located at the second station is arranged horizontally. Based on this, when the jacking device 200 lifts the cargo box to be close to the conveyor line 120 located at the second station, the opening of the cargo box can be easily closed by the conveyor line 120 located at the second station, and the cargo box can be prevented from tipping over.

[0030] As described above, in the turning machine 10, the input line 300 can transport the cargo box containing fruits and vegetables to the conveyor line 120 located at the first station; after the cargo box containing fruits and vegetables is transported to the conveyor line 120 located at the first station, the cargo box containing fruits and vegetables can be lifted by the lifting device 200 to fit with the conveyor line 120 located at the second station, so as to close the opening of the cargo box through the conveyor line 120. Then, the two conveyor lines 120 are driven to turn over by the turning drive device 110, so that the conveyor line 120 located at the second station can be turned over to the first station, and at this time, the cargo box pressed under the conveyor line 120 is turned over to the top of the conveyor line 120 and presents an inverted state, so that the fruits and vegetables in the cargo box can be poured out, and the pouring of fruits and vegetables can be realized. Finally, the fruits and vegetables can be output from the output line 400. Based on this, the dumping of fruits and vegetables can be completed automatically, and the dumping efficiency is improved; and during the flipping process, since the cargo box is closed by the conveyor line 120, the fruits and vegetables can be prevented from falling, thereby preventing the problem of fruits and vegetables falling and being damaged. Therefore, the flipping machine 10 can improve the technical problems of low efficiency of dumping fruits and vegetables in cargo boxes and easy damage to fruits and vegetables in the prior art.

[0031] It should be noted that both conveyor lines 120 have motors operated by controllers, and the motors of the two conveyor lines 120 operate independently to drive the two conveyor lines 120 to operate respectively. Figure 1 The straight arrow on the middle conveying line indicates the conveying direction of the conveying line 120 , while the curved arrow on the periphery of the flip driving device 110 indicates the direction in which the flip driving device 110 drives the two conveying lines 120 to rotate.

[0032] In addition, after the fruits and vegetables are emptied from the cargo box, the empty cargo box can be clamped by the adaptive device and placed on the conveyor line 120 located at the second station for transportation; and since the conveying directions of the two conveyor lines 120 are opposite, the empty cargo box can be transported toward the source of goods, which is convenient for reuse and reduces costs.

[0033] Optionally, in this embodiment, the lengths of the two conveyor lines 120 are equal. Based on this, after the two conveyor lines 120 switch positions, it can be ensured that the conveyor line 120 located at the first station can stably connect with the input line 300 and the output line 400, facilitating the input of cargo boxes and the output of fruits and vegetables.

[0034] In this embodiment, the lifting device 200 is a cylinder telescopic device.

[0035] In addition, in this embodiment, the turnover machine 10 further includes a first gap monitoring device, which is disposed between the conveyor line 120 and the input line 300 at the first station and is located below the conveyor line 120; the first gap monitoring device is used to monitor and record the number of cargo boxes passing between the input line 300 and the conveyor line 120 before the turnover drive device 110 is operated. In other words, the number of cargo boxes input from the input line 300 to the conveyor line 120 can be monitored by the first gap monitoring device, so as to facilitate the determination of the number of cargo boxes on the conveyor line 120 at the first station.

[0036] Furthermore, the turning machine 10 further includes a second gap monitoring device, which is disposed between the conveyor line 120 and the output line 400 at the first station and is located below the conveyor line 120; the second gap monitoring device is used to monitor the fruits and vegetables passing between the conveyor line 120 and the output line 400 after the turning drive device 110 is operated. In other words, the fruits and vegetables output from the conveyor line 120 can be monitored by the second gap monitoring device, so as to facilitate the judgment of whether the fruits and vegetables on the conveyor line 120 at the first station have been output, and thus facilitate the execution of the next turning operation.

[0037] See also Figure 2 Based on the above-mentioned turning machine 10, this embodiment further provides a turning control method, which is applied to the above-mentioned turning machine 10. In other words, the turning machine 10 can execute the turning control method in this embodiment to achieve the purpose of improving the technical problems of low efficiency of dumping fruits and vegetables in the cargo box and easy damage to fruits and vegetables.

[0038] It should be noted that the turning machine 10 has a control module, and the control module can be used to execute the turning control method to control the above components in the turning machine 10 to realize corresponding functions.

[0039] In this embodiment, the flip control method includes: S1. Control the input line 300 to transport the cargo box to the conveyor line 120 located at the first station.

[0040] S2. When the input line 300 inputs the cargo box to the preset position, the two conveying lines 120 are controlled to stop conveying.

[0041] S3, controlling the lifting device 200 on the conveyor line 120 located at the first station to lift the cargo box until the opening of the cargo box contacts the conveyor line 120 located at the second station.

[0042] S4, controlling the flip driving device 110 to operate to flip the two conveying lines 120 so that the two conveying lines 120 switch positions.

[0043] S5. Control the adaptive device to clamp the cargo box on the conveyor line 120 located at the first station, and move the cargo box to above the conveyor line 120 located at the second station.

[0044] S6. After the cargo box is moved to the conveyor line 120 located at the second station, the two conveyor lines 120 are controlled to operate so as to output the empty cargo box through the conveyor line 120 located at the second station, and receive fruits and vegetables through the output line 400 to output the fruits and vegetables.

[0045] S7, returning to the step of controlling the input line 300 to convey the boxes to the conveying line 120 located at the first station until a preset number of boxes are processed.

[0046] Wherein, step S7 can also be represented as returning to step S1 to perform the flipping operation in a loop until the flipping process of a preset number of cargo boxes is completed. The preset number can be a parameter input manually. It should be understood that in other embodiments, the preset number can also be input as all cargo boxes.

[0047] As described above, when the turning machine 10 executes the turning control method, it can automatically turn over the cargo box to dump the fruits and vegetables, thereby efficiently completing the dumping operation of the fruits and vegetables.

[0048] It is worth noting that in the above-mentioned flip control method, such as step S3 and step S4, when the lifting device 200 lifts the cargo box to contact the conveyor line 120 of the second station, the operation of the flip drive device 110 in step S4 can be triggered, that is, the controller can trigger the execution control of step S4 based on the completion of step S3. Of course, it can also be regarded as that the controller can trigger the operation control of the flip drive device 110 based on the operation state of the lifting device 200. Similarly, the controller can also trigger the extension of the lifting device 200 in step S3 based on whether the conveyor line 120 has completed the stop and formed a state of stopped transportation during the execution of step S2. In other words, the controller can identify the current state of the flip machine 10, and execute the corresponding steps based on the identified current state of the flip machine 10, so that the logic of the flip control method is more reasonable, the operation of the flip machine 10 is smoother, and the phenomenon of jamming is avoided.

[0049] Optionally, when the turning machine 10 is further provided with a first gap monitoring device, the turning control method further includes: Before the step of controlling the lifting device 200 on the conveyor line 120 located at the first station to lift the cargo box until the opening of the cargo box contacts the conveyor line 120 located at the second station, that is, before step S3, it is determined whether the number of cargo boxes input into the conveyor line 120 is greater than 1.

[0050] First, if the number of cargo boxes input into the conveyor line 120 is greater than 1, the turning machine 10 is controlled to stop and an alarm signal is issued. It is worth noting that in the embodiment of the present application, each conveyor line 120 is provided with a corresponding lifting device 200, so that only one cargo box can be lifted; if multiple cargo boxes are transported on the conveyor line 120, fruits and vegetables in some of the cargo boxes will fall during the turning process. Therefore, in general, in one turning operation, only one cargo box is transported to the conveyor line 120 of the first station to facilitate the orderly dumping of fruits and vegetables.

[0051] Secondly, if the number of cargo boxes input into the conveyor line 120 is equal to 1, the step of controlling the lifting device 200 on the conveyor line 120 at the first station to lift the cargo box until the opening of the cargo box contacts the conveyor line 120 at the second station is executed. That is, when only one cargo box is input into the conveyor line 120 at the first station, step S3 can be started.

[0052] Further, based on the above judgment, if the number of cargo boxes input into the conveyor line 120 is less than 1 and lasts for the first preset time, the turning machine 10 is controlled to stop. That is, after the first preset time, the conveyor line 120 still does not detect the input of cargo boxes. At this time, there may be two situations: all cargo boxes have been processed, or the turning machine 10 has a fault. At this time, the turning machine 10 is controlled to stop, one is to stop after the operation is completed, and the other is to facilitate maintenance if the turning machine 10 fails.

[0053] Optionally, in this embodiment, a sensor for detecting whether the cargo box reaches a preset position is provided on the conveyor line 120, and the sensor may be a photoelectric sensor or an infrared sensor.

[0054] In this embodiment, when a second gap monitoring device is further provided on the turning machine 10, the turning control method further includes: Before returning to the step of controlling the input line 300 to transport the cargo box to the conveyor line 120 at the first station until the preset number of cargo boxes are processed, it is determined whether the time that the fruits and vegetables last passed through the gap between the conveyor line 120 and the output line 400 has reached the second preset time. That is, after the cargo box is turned over, the fruits and vegetables are poured out of the cargo box and transported on the conveyor line 120 at the first station to be transported to the output line 400. The second gap monitoring device can detect the fruits and vegetables transmitted from the conveyor line 120 to the output line 400, so that it can be determined by the detection of the second gap monitoring device to know whether the fruits and vegetables on the conveyor line 120 have been output.

[0055] Among them, if the judgment result is that the time that the fruits and vegetables last passed through the gap between the conveyor line 120 and the output line 400 reaches the second preset time, it means that the fruits and vegetables on the conveyor line 120 have been output, and the step of returning to control the input line 300 to transport the cargo boxes to the conveyor line 120 located at the first workstation is executed until the preset number of cargo boxes are processed; that is, the above-mentioned step S7 is executed.

[0056] In addition, if the judgment result is that the time that the fruits and vegetables last passed through the gap between the conveyor line 120 and the output line 400 does not reach the second preset time, the conveyor line 120 is controlled to continue running to continuously output the fruits and vegetables on the conveyor line 120.

[0057] Optionally, the flip control method further includes: After the step of controlling the flip driving device 110 to operate and flip the two conveyor lines 120 so that the two conveyor lines 120 switch positions, it is determined whether the two conveyor lines 120 are located at the first station and the second station, respectively. In other words, it is determined whether the two conveyor lines 120 move into position, that is, whether one of the conveyor lines 120 accurately enters the first station, and whether the other conveyor line 120 accurately enters the second station.

[0058] If the two conveyor lines 120 are respectively located at the first station and the second station, the step of controlling the adaptive device to clamp the cargo box on the conveyor line 120 located at the first station and move the cargo box to above the conveyor line 120 located at the second station is executed; that is, after the two conveyor lines 120 are flipped into place, the above-mentioned step S5 can be executed.

[0059] Of course, if the two conveyor lines 120 are not located at the first station and the second station, the flip drive device 110 is controlled to continue to operate until the two conveyor lines 120 are flipped into place, that is, respectively located at the first station and the second station.

[0060] In summary, the turning machine 10 and the turning control method provided in the embodiment of the present application, the input line 300 can transport the cargo box containing fruits and vegetables to the conveyor line 120 located at the first station; after the cargo box containing fruits and vegetables is transported to the conveyor line 120 located at the first station, the cargo box containing fruits and vegetables can be lifted by the lifting device 200 to fit with the conveyor line 120 located at the second station, so as to close the opening of the cargo box through the conveyor line 120. Then, the two conveyor lines 120 are driven to turn over by the turning drive device 110, so that the conveyor line 120 located at the second station can be turned over to the first station, and at this time, the cargo box held under the conveyor line 120 is turned over to the top of the conveyor line 120 and presents an inverted state, thereby pouring out the fruits and vegetables in the cargo box, and realizing the dumping of fruits and vegetables. Finally, the fruits and vegetables can be output from the output line 400. Based on this, the dumping of fruits and vegetables can be completed automatically, and the dumping efficiency can be improved; and in the flipping process, since the cargo box is closed by the conveyor line 120, the fruits and vegetables can be prevented from falling, thereby avoiding the problem of fruits and vegetables falling and being damaged. Therefore, the flipping machine 10 can improve the technical problems of low efficiency of dumping fruits and vegetables in the cargo box and easy damage to fruits and vegetables in the prior art. In addition, the controller can identify the current state of the flipping machine 10, and execute corresponding steps based on the identified current state of the flipping machine 10, so that the logic of the flipping control method is more reasonable, the operation of the flipping machine 10 is smoother, and the phenomenon of jamming is avoided.

[0061] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
