The second conveyor belt is driven by a servo motor, and only advances by a fixed stroke at each time in an intermittent control mode, and the fixed stroke only allows one tray to be conveyed to the first conveyor belt. Specifically, the fixed stroke is determined by the spacing between two adjacent trays.

S2, conveying the tray 1 along the lifting path 2;

in order to transport the pallet 1, a lifting platform 21 is arranged in the lifting channel 2, and the lifting platform 21 can move up and down along the lifting channel 2 and is driven by a linear rail.

S3, distinguishing the orientation of the tray 1 when the tray is conveyed to a predetermined height; if the tray is right side up, go to S4, otherwise go to S5;

in this embodiment, the method for distinguishing the orientation of the tray 1 is as follows:

s31, arranging a pressure sensor 4 on the side wall of the lifting channel 2, wherein the position of the pressure sensor 4 can be adjusted according to the height of the tray 1, and the optimal position meets the following conditions: when the lifting platform 21 is lowered to the specified height of the stroke, the folded edge 11 of the tray 1 placed in the forward direction is not contacted with the pressure sensor 4, and as shown in fig. 4, the folded edge 11 of the tray 1 placed in the reverse direction is pressed against the pressure sensor 11; so that the front and back orientations of the tray can be distinguished by the signals fed back by the pressure sensors 4.

S32, when the lifting platform 21 descends to the predetermined height, if the pressure sensor 4 receives the pressure signal, it is determined that the tray 1 is facing downward, otherwise, it is determined that the tray 1 is facing upward.

In order to realize the height adjustment of the pressure sensor, the pressure sensor device further comprises a height adjusting device for adjusting the height of the pressure sensor 4, and the pressure sensor 4 is arranged on the height adjusting device. Specifically, referring to fig. 4 and 5, a slot is vertically formed in the side wall of the lifting channel 2, the height adjusting device includes a screw 81 and a slider 82 which are arranged in the slot, and the screw 1 is rotatably arranged in the slot and is driven to rotate by a motor; the sliding block 82 is connected with the groove in an up-and-down sliding mode and is in threaded fit with the screw rod 1, and the pressure sensor 4 is fixedly arranged on the sliding block 82. With the rotation of the screw rod 1, the slide block 82 drives the pressure sensor 4 to slide upwards or downwards.

After distinguishing the orientation of the tray 1, the tray 1 needs to be conveyed in different directions, so that the first conveying belt 22 is arranged on the lifting platform 21, the first conveying belt 22 is driven by a servo motor, and the conveying direction of the first conveying belt can be changed through pulse signals.

Because the size of tray 1 differs, if tray 1 is less, it has certain distance to probably lead to tray 1 and the lateral wall of installing pressure sensor 4 that get into in the lift passageway, and at this moment, in time be the tray 1 of reverse placing, also can not trigger pressure sensor 4 at the descending in-process, lead to the orientation of unable discernment tray 1. In order to avoid this situation, this scheme inclines first conveyer belt 22 towards pressure sensor 4 one side for tray 1 on first conveyer belt 22 supports constantly and presses on the lateral wall of pressure sensor 4 one side, guarantees that the tray 1 of placing in reverse can trigger pressure sensor 4 in the in-process that descends.

In order to realize automatic control, the automatic control device further comprises a controller which is electrically connected with the pressure sensor 4 and a motor for driving the first conveyor belt 22 to move. As shown in fig. 5, when the elevating table 21 is lowered to the lowest position, the first conveyor belt 22 is driven to convey the tray 1 in the first direction if the pressure sensor 4 detects the pressure; as shown in fig. 4, if the pressure sensor 3 does not detect the pressure, the first conveyor belt 22 is driven to convey the tray 1 in the second direction; thereby achieving diversion of trays 1 of different orientations.

S4, the tray 1 is conveyed to the storage box 6 with the first slope kept right side up. Referring to fig. 6, the first ramp 51 is disposed at a first side of the first conveyor belt 22 at the lowest position, and is used for conveying the tray 1 into the storage box 6. Specifically, the top of the first ramp 51 is connected to the right side of the first conveyor belt 22, and the bottom of the first ramp 51 extends to the storage box 6. Referring to fig. 5, in operation, the first conveyor belt 22 conveys the tray 1 to the right to the outer side surface of the first ramp 51 (the side surface away from the first conveyor belt 22), and the tray 1 slides along the first ramp 51 toward the storage box 6 with the opening inclined upward until falling into the storage box 6.

S5, the orientation of the tray 1 is reversed by the second slope 52 and then the tray is conveyed to a storage box. Referring to fig. 7, the second ramp 52 is disposed at a second side of the first conveyor belt 22 at the lowest position, and is used for transferring the tray 1 into the storage box 6 after being turned over. Specifically, the top of the second ramp 52 is spaced from the left side of the first conveyor belt 22 to form a turning channel for turning the tray 1, and the bottom of the second ramp 52 extends to the storage box 6. Referring to fig. 6, in operation, the first conveyor belt 22 conveys the tray 1 to the left to the inner side surface of the second ramp 52 (the side surface facing the first conveyor belt 22), the tray 1 is turned to an angle with the opening inclined upward in the turning channel, and then slides along the first ramp 51 toward the storage box 6 until the tray falls into the storage box 6.

In order to ensure the smoothness of the turning process of the second ramp 52, a plurality of turning rollers 7 are arranged in the turning channel, the turning rollers 7 are distributed from the second side of the first conveyor belt 22 to the second ramp 52 in an arc shape, and the distance between the turning rollers 7 and the second ramp 52 is gradually reduced.
