[0032] In addition, as Figure 1As shown: the prior art cattail tray 11 is transported on the conveying platform 30, the roller 4 is driven by the driving motor 32, and then drives the cattail tray 11 to be transported, the stop tray 2 includes the baffle 210 and the elevator 220, when the cattail tray 11 reaches the bottom of the cattail packaging device for cattail transmission, the baffle 210 of the stop tray 2 is lifted by the elevator 220, the baffle 210 separates the cattail tray 11, and the cattail is filled, but at this time, the driving motor 32 is still working, the cattail tray 11 on the left side separated by the stop tray 2 is always transmitted by left and right friction, causing the continuous wear of the bottom of the cattail tray 11, when the cattail is completely filled in the cattail tray 11, the elevator 220 drives the baffle 210 to descend, and the filled cattail tray 11 continues to be transported on the conveying platform 30 to transport the cattail out.

[0033] Further, the conveying assembly comprises a conveying platform 30 and a first tray support assembly 51 and a second tray support assembly 52 spaced below the conveying platform 30, the conveying platform 30 is provided with a plurality of conveying rollers 31 arranged in parallel, a spacing is provided between any two adjacent conveying rollers 31, the first tray support assembly 51 and the second tray support assembly 52 can be lifted through the spacing, the conveying platform 30 has a first station section 41 corresponding to the first tray support assembly 51 and a second station section 42 corresponding to the second tray support assembly 52 in the conveying direction of the conveying platform 30, and the ends of the first station section 41 and the second station section 42 are provided with a position sensor group 70, the first tray support assembly 51, the second tray support assembly 52 and the two position sensor groups 70 are electrically connected with each other.

[0034] When the first end of the first station section 41 detects the information of the day lily tray 11 through the arrival sensor group 70, the day lily tray 11 on the conveying platform 30 continues to be conveyed to the second station section 42, and when the second end of the second station section 42 detects the information of the day lily tray 11 through the arrival sensor group 70, the detected information of the day lily tray 11 is transmitted to the second tray supporting assembly 52 below the second station section 42, the lifting drive 521 below the second tray supporting assembly 52 is started to lift the day lily tray 11 on the second station section 42 to start containing the day lily; when the day lily tray 11 is conveyed to the first station section 41, the first end of the first station section 41 detects the information of the day lily tray 11 through the arrival sensor group 70, and the information of the day lily tray 11 is transmitted to the first tray supporting assembly 51 below the first station section 41. The lifting drive 521 below the first tray supporting assembly 51 is started to lift the day lily tray 11 on the first station section 41, and the day lily tray 11 is lifted from the conveying roller 31 of the conveying platform 30 through the first tray supporting assembly 51 and the second tray supporting assembly 52 to avoid the continuous contact between the day lily tray 11 and the conveying roller 31 during the conveying process, which causes the wear of the bottom of the day lily tray 11.

[0035] Further, the feeding clamping gripper 20 specifically comprises a first base 21, a first mechanical arm 22 and a first clamping head 23. The first mechanical arm 22 is arranged above the first base 21, a driving motor is arranged on the first mechanical arm 22 to drive the first mechanical arm 22 to rotate, the first clamping head 23 is arranged at the end of the first mechanical arm 22, a plurality of clamping suction cups 231 are arranged on the first clamping head 23, a negative pressure fan is arranged on the first base 21, and a plurality of negative pressure air pipes are arranged on the first clamping head 23. One end of the negative pressure air pipe is connected with the clamping suction cup, and the other end of the negative pressure air pipe is connected with the negative pressure fan. The negative pressure fan generates negative pressure suction force on the clamping suction cup 231, and then the clamping suction cup 231 adsorbs and clamps the day lily tray 11. By arranging the feeding clamping gripper 20 on the feeding side of the conveying platform 30, the day lily tray 11 is automatically clamped and placed on the conveying platform 30 by the feeding clamping gripper 20, which avoids manual placement of the day lily tray 11 and saves labor.

[0036] Further, the first tray supporting assembly 51 and the second tray supporting assembly 52 each comprises a lifting driving member 521, a cross plate 522 and two supporting plates 523, the lifting driving member 521 is arranged below the conveying platform 30, the cross plate 522 is arranged at the output end of the lifting driving member 521 and is located between the lifting driving member 521 and the conveying platform 30, the two supporting plates 523 are arranged at the side of the cross plate 522 away from the lifting driving member 521 in the conveying direction, the arrangement interval of the two supporting plates 523 is less than the length of the day lily tray 11 in the conveying direction, the two supporting plates 523 can be lifted synchronously through the two intervals, and the lifting driving member 521 is electrically connected with the two position sensor groups 70.

[0037] The position information of the day lily tray 11 transmitted to the first station section 41 and the second station section 42 is detected by the position sensor group 70 arranged on the conveying platform 30, and then the position information is transmitted to the lifting driving member 521 below the first tray supporting assembly 51 and the second tray supporting assembly 52, the lifting driving member 521 is started, thereby driving the first tray supporting assembly 51 and the second tray supporting assembly 52 to lift, and the day lily tray 11 is lifted from the conveying platform 30, so as to avoid the continuous abrasion of the day lily tray 11 on the conveying roller 31.

[0038] In addition, the loading weight of the day lily tray 11 on the second station section 42 cannot be accurately detected during the transmission process above the conveying platform 30, which is easy to cause the day lily in the day lily tray 11 on the second station section 42 to be overfilled or underfilled.

[0039] In order to avoid such situations, further, the weight sensor 524 is arranged on the upper end surface of the two supporting plates 523, and the weight sensor 524 is electrically connected with the lifting driving member 521.

[0040] By arranging the weight sensor 524 on the upper end surface of the supporting plate 523 of the second tray supporting assembly 52, the loading weight of the day lily can be detected in real time during the process of filling the day lily into the day lily tray 11, and the weight signal upper and lower limit value of the weight sensor 524 is set to 9.5kg to 10.5kg when the weight of the day lily filled in the day lily tray 11 reaches this range, the weight signal is transmitted to the lifting driving member 521 below the second tray supporting assembly 52, the lifting driving member 521 is started to drive the day lily tray 11 to descend to the horizontal plane of the conveying platform 30, and then the day lily tray 11 filled with day lily is conveyed out through the conveying platform 30.

[0042] Since the day lily tray 11 needs to be lifted from the conveying roller 31 of the conveying platform 30 through the two support plates 523 below the first tray support assembly 51 and the second tray support assembly 52 during the conveying process, to avoid continuous friction of the day lily tray 11 on the conveying roller 31, to avoid the support plate 523 from slipping when lifting the day lily tray 11, the bottom of the day lily tray 11 is provided with two limiting grooves 111 vertically spaced apart in the direction perpendicular to the conveying direction, and the support plate 523 corresponds to the limiting groove 111 at the bottom of the day lily tray 11, so as to avoid the support plate 523 from slipping when lifting the day lily tray 11.

[0043] Further, the in-place sensor group 70 includes a first in-place sensor 71, a second in-place sensor 72, and a fixed rod 73, the fixed rod 73 is arranged on the outer side frame of the conveying platform 30, the first in-place sensor 71 and the second in-place sensor 72 are respectively arranged in the height direction and spaced apart from the fixed rod 73, and the first tray support assembly 51, the second tray support assembly 52, the first in-place sensor 71, and the second in-place sensor 72 are electrically connected with each other, the first in-place sensor 71 corresponds to the conveying plane of the conveying platform 30, the second in-place sensor 72 of the first workpiece section 41 corresponds to the height position of the first tray support assembly 51 in the extended state, so as to ensure that the day lily tray 11 can be detected when being lifted and lowered by the lifting driving member 521, and the second in-place sensor 72 of the second workpiece section 42 corresponds to the height position of the second tray support assembly 52 in the extended state.

[0044] When the second-to-position sensor 72 and the first-to-position sensor 71 of the second station section 42 do not detect the information of the day lily tray 11 during the conveying of the day lily tray 11 on the conveying platform 30, the day lily tray 11 on the first station section 41 continues to be conveyed forward on the conveying platform 30, and when the day lily tray 11 is conveyed to the second station section 42, the first-to-position sensor 71 of the second station section 42 detects the signal of the day lily tray 11 and transmits the signal to the lifting drive 521 below the second tray supporting assembly 52, so that the lifting drive 521 is started to drive the second tray supporting assembly 52 to be lifted, and when the day lily tray 11 on the second station section 42 is filled with the day lily, the second tray supporting assembly 52 detects the weight change through the supporting plate 523, transmits the weight signal to the lifting drive 521 below the second tray supporting assembly 52, so that the day lily tray 11 on the second station section 42 is lowered, and is conveyed out through the conveying platform 30.

[0045] Specifically, in another embodiment, the to-position sensor group 70 is a light curtain sensor, the maximum extension position of the first tray supporting assembly 51 and the second tray supporting assembly 52 is the first position, and the detection height of the light curtain sensor is from the conveying plane of the conveying platform 30 to the first position.
