When the bag is to be taken out of the warehouse, firstly, the telescopic cylinder 23a of the telescopic mechanism 23 is pulled backwards, the supporting tongues 20 are pulled to be contracted towards the left and right outer sides of the bag warehouse 10, then the lifting cylinder 15 pushes the lifting frame 16 downwards, so that the supporting plates 13 in the whole bag warehouse 10 are simultaneously descended under the support of the L-shaped hooks 16a, when the height of the lowest layer supporting plate 13 is lower than that of the supporting tongues 20, the telescopic cylinder 23a extends out, the supporting tongues 20 are pushed to extend towards the inner side of the bag warehouse 10, the lifting cylinder 15 drives the plurality of supporting plates 13 and the packaging bags 14 thereon to continue descending, so that the second layer supporting plate 13 from bottom to top is supported by the L-shaped supporting tongues 20 and does not descend any more, the lowest layer supporting plate 13 and the packaging bags 14 thereon continue descending under the support of the L-shaped hooks 16a until the lowest layer supporting plate 13 is placed on the conveyor belt 11 to stop descending, and then the lifting cylinder, then, the opening and closing cylinder 17a of the opening and closing mechanism 17 retracts towards two sides, the L-shaped hook 16a is pulled to open towards two sides through the U-shaped connecting piece 17b and the traction pin 24, the L-shaped hook 16a leaves the supporting plate 13 on the conveyor belt 11, then the lifting cylinder 15 rises again, the lifting frame 16 is pulled to rise, when the transverse hook of the L-shaped hook 16a is higher than the height of the supporting plate on the conveyor belt 11, the opening and closing cylinder 17a is pushed out, the L-shaped hook 16a is pushed to close through the U-shaped connecting piece 17b and the traction pin 24, and the transverse hook of the L-shaped hook 16a enters the inner side of the bag warehouse 10; then, the lifting cylinder 15 continues to rise until the lifting cylinder 15 is in place and stops, and returns to the original position, at this time, the L-shaped hooks 16a of the lifting frame 16 hang up the plurality of supporting plates 13 and the packaging bags 14 on the supporting plates again, so that the L-shaped supporting tongues 20 do not support the supporting plates 13; then, the conveyor belt 11 starts to run, the supporting plate 13 placed on the conveyor belt 11 and the packaging bags 14 on the supporting plate run out of the warehouse under the driving of the conveyor belt 11, and the packaging bags are discharged out of the warehouse; when the pallet 13 on the conveyor belt 11 and the packaging bag 14 thereon run to the end position of the conveyor belt 11 and then stop running, at this time, the second pallet 13 and the packaging bag 14 thereon can be conveyed onto the conveyor belt 11 on the conveyor belt 11 under the bag warehouse 10, when the packaging bag 14 at the end position of the conveyor belt 11 is taken out, the conveyor belt 11 runs again, the empty pallet 13 at the end position is sent out, the second pallet 13 is sent to the end position of the conveyor belt 11, then, the conveyor belt stops, at this time, the third pallet 13 can be taken out from the bag warehouse 10, and the rest process is circulated repeatedly.

By arranging the bag warehouse 10 above the starting end of the conveyor belt 11, the supporting plate 13 placed in the bag warehouse 10 and the packaging bag 14 arranged above the supporting plate can be descended onto the conveyor belt 11 along the vertical direction, so that the conveyor belt 11 can convey the supporting plate 13 and the packaging bag 14 placed above the supporting plate to the terminal position of the conveyor belt 11; by designing the bag warehouse 10 into a frame structure, the supporting plates 13 can be placed in the bag warehouse 10 from top to bottom, so that the plurality of supporting plates 13 placed in the bag warehouse 10 and the packaging bags 14 arranged above the supporting plates can descend from top to bottom, a single supporting plate 13 below and the packaging bags 14 above the supporting plate can be horizontally placed on the conveying belt, and the packaging bags 14 can be conveyed to the terminal position of the conveying belt 11; particularly, the supporting plate 13 is arranged to be in an I-shaped structure, so that the positioning of the supporting plate 13 is facilitated, the carrying of the supporting plate 13 is facilitated, and a hand or a carrying tool can be inserted from the middle of two sides during carrying; the lifting frames 16 and the supporting tongues 20 are arranged at two sides of the storage frame of the bag warehouse 10, the L-shaped hooks 16a are hinged below the lifting frames 16, the L-shaped hooks 16a are favorable for supporting the plurality of supporting plates 13 and the packaging bags 14 thereof to descend, when the supporting tongues 20 retract to two sides, the descending of the plurality of supporting plates 13 and the packaging bags 14 thereof is not hindered, when the lowest layer supporting plate 13 descends and the height thereof is lower than the height of the supporting tongues 20, the supporting tongues 20 extend out of the warehouse by utilizing the telescopic mechanism 23, the supporting plates 13 continue to descend, the supporting tongues 20 can lift and support the second layer supporting plate 13, all the supporting plates 13 and the packaging bags 14 thereof above the second layer stop descending, the L-shaped hooks 16a hang the lowest layer supporting plate 13 and the packaging bags 14 above the lowest layer supporting plate 13 under the driving of the lifting air cylinder 15, the lowest layer supporting plate 13 and the packaging bags 14 above the lowest layer supporting plate, when the pallet detection switches arranged on two sides of the transmission belt 11 detect that the pallet 13 descends to the right position, the opening and closing mechanism 17 opens the L-shaped hook 16a, under the condition, only if the length of the pallet 13 is larger than the width of the transmission belt 11, the opening and closing mechanism is favorable for the opening of the L-shaped hook 16a to be separated from the lower part of the pallet 13, then the L-shaped hook 16a is driven by the lifting cylinder 15 to ascend, when the height of the L-shaped hook 16a exceeds the height of the pallet 13 placed on the transmission belt 11, the opening and closing mechanism 17 closes the L-shaped hook 16a, the L-shaped hook 16a continues to ascend under the drive of the lifting cylinder 15 and returns to the original position, the L-shaped hook 16a can hook the pallet 13 originally supported by the support tongue 20, and the support tongue 20 is suspended; then, the conveyor belt 11 is started, and when the supporting plate 13 and the packaging bags 14 placed on the supporting plate reach the end position of the conveyor belt 11, the conveyor belt 11 stops rotating; the long hole 16b is formed in the vertical rod of the L-shaped hook 16a, so that a traction pin 24 of the opening and closing mechanism 17 can horizontally penetrate through the long hole, the traction pin 24 enables the L-shaped hook 16a to be opened and closed under the driving of the opening and closing cylinder 17a, and the long hole 16b is beneficial to enabling the vertical rod of the L-shaped hook 16a to slide up and down along the traction pin 24 when the lifting cylinder 15 drives the L-shaped hook 16a to lift due to the fact that the height of the traction pin 24 is unchanged; the packaging bag detection hole 27 is formed in the supporting plate 13, so that the packaging bag 14 can be detected to be completely taken out, and the conveying belt 11 can be used for conveying the empty supporting plate 13 out; the lifting frame 16 is provided with the height detection switch of the bottom layer supporting plate 13, so that the telescopic control of the supporting tongue 20 is guaranteed; the opening and closing mechanism 17 and the telescopic mechanism 23 are arranged in the frames 12a on the left side and the right side of the bag warehouse 10 and are matched with each other, so that the lower layer supporting plate 13 and the packaging bags 14 placed on the lower layer supporting plate are favorably placed on the conveyor belt 11, and whether the supporting plate 13 is placed on the conveyor belt 11 or not is favorably detected by arranging the detection switches right below the supporting plates on the two sides of the conveyor belt 11; by arranging the end point detection switch of the conveyor belt 11 and the packaging bag taking-out detection switch, whether the supporting plate 13 runs in place or not and whether the empty supporting plate 13 is sent out or not are favorably controlled.
