Description

Technical Field

[0001] The present invention relates to the field of color carton transportation technology, and more specifically, to an automatic palletizing device for color carton Background Art

[0002] As an indispensable element in the field of packaging and logistics, colored cartons are extremely common in people's daily lives and the demand for them continues to rise. They are not only widely used in the packaging of various commodities, but also bear the important responsibility of protecting commodities and enhancing product image. In the production and circulation of cartons, in order to effectively promote transportation efficiency and rational use of storage space, ensuring that cartons can be stacked safely and stably, the so-called "palletizing", has become a crucial part of the production process.

[0003] In the prior art, colored cartons are often stacked in one direction. However, this single stacking method has a significant defect, that is, the stacked colored cartons are prone to tipping over due to lack of sufficient mutual support. By stacking in a horizontal and vertical alternating arrangement, a tighter and interlocking structure can be formed, thereby significantly improving the overall anti-tipover ability of the stacking. Therefore, the colored cartons need to be transported horizontally and vertically to facilitate stacking. Summary of the invention

[0004] In view of the shortcomings of the prior art, the object of the present invention is to provide an automatic stacking device for colored paper boxes.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: an automatic stacking device for color paper boxes, comprising a frame, a conveying mechanism is provided on the frame, and the conveying mechanism includes a conveyor belt for conveying color paper boxes, characterized in that: a side plate 1 parallel to the conveyor belt is provided on one side of the frame, and a guide inclined plate is provided at the end of the side plate 1, and a side plate 2 parallel to the side plate 1 is slidably provided on the other end of the frame, two slide grooves are provided on the side plate 2, and a displacement inclined plate is provided at the end of the side plate 2, and the displacement inclined plate is closer to the feeding end of the conveying mechanism than the guide inclined plate; two swing arms are rotatably provided on one side of the frame close to the side plate 2, and a sliding column is provided at the end of the swing arm, and the two sliding columns respectively form a sliding fit with the two slide grooves, and a connecting rod is fixedly provided under the rotating shaft of the swing arm, and the two connecting rods are jointly hinged with a flat rod, and a displacement cylinder is provided at the end of the flat rod, and the telescopic shaft end of the displacement cylinder is hinged to the end of the flat rod, and the base of the displacement cylinder is hinged to the side of the frame.

[0006] As a preferred technical solution of the present invention, an attached plate is fixedly provided on one side of the frame close to the side plate, a pushing motor is arranged on the attached plate, a pushing screw is connected to the rotating shaft of the pushing motor, a sliding seat is slidably provided on the attached plate, and a threaded fit is formed with the pushing screw in the middle of the sliding seat, a connecting column is vertically provided on the sliding seat, a push plate is provided at the end of the connecting column, and the push plate includes a flat push plate and a side baffle which are perpendicular to each other.

[0007] As a preferred technical solution of the present invention, a lifting mechanism is provided on the side of the frame close to the second side plate, the lifting mechanism includes a lifting seat and a lifting plate, and a pallet plate for stacking colored cartons is placed on the lifting plate.

[0008] As a preferred technical solution of the present invention, an insert plate is provided on the upper side of the push plate, an aligning frame is provided on the frame and directly above the lifting mechanism, two side slide plates are symmetrically slidably provided in the aligning frame, side aligning plates for clamping the aligning colored paper boxes are vertically provided on the side slide plates, middle support plates are provided on the side aligning plates, and tension springs are connected between the two middle support plates; an arc structure is provided at the end of the middle support plate, and the end of the insert plate is a double-bevel structure for driving the arc structure of the middle support plate.

[0009] As a preferred technical solution of the present invention, a sliding base is provided directly below the lifting mechanism, a sliding motor is provided on the sliding base, a sliding screw is connected to the end of the rotating shaft of the sliding motor, and the sliding base forms a sliding fit with the lifting seat of the lifting mechanism, and the lifting seat forms a threaded fit with the sliding screw.

[0010] As a preferred technical solution of the present invention, a positioning platform for positioning the pallet plate is provided at the edge of the lifting plate of the lifting mechanism, two latches are symmetrically slidably provided on the positioning platform, a latch spring is connected between the two latches, the end of the latch is a round head, and notches are provided on the positioning platform and at the round heads of the latches.

[0011] As a preferred technical solution of the present invention, a storage box for storing pallet plates is provided above the sliding base, and the four inner walls of the storage box are provided with inner plates, and the upper ends of the inner plates are inclined structures. The outlet of the storage box is located directly above the sliding base, and two sliding blocking rods are provided at the outlet of the storage box for parallel sliding. The end of the sliding blocking rod close to the lifting mechanism is a vertical support rod, and the other ends of the sliding blocking rods are connected together with a joint plate.

[0012] As a preferred technical solution of the present invention, the lifting plate of the lifting mechanism is slidably provided with side plates on both sides perpendicular to the positioning platform, top plates are vertically provided at the ends of the side plates, the upper surfaces of the side plates and the edges close to the central axis of the lifting plates are all inclined structures, clamping springs are connected between the side plates and the lifting plates, and a shift rod is provided under the side plates; wedge blocks for driving the shift rod are provided on both sides of the sliding base.

[0013] The beneficial effects of the present invention compared with the prior art are:

[0014] 1. The present invention moves toward the warehouse box through the lifting mechanism. When the lifting plate moves to the bottom of the warehouse box outlet, the slide bar no longer blocks the pallet plate, and the pallet plate in the warehouse box automatically falls onto the lifting plate of the lifting mechanism, thereby completing the automatic placement of the pallet plate and facilitating the continuous automatic stacking of colored cartons.

[0015] 2. When the pallet plate of the present invention falls from the warehouse box onto the lifting plate, the pallet plate falls to the middle position of the side plate, the top plate and the positioning platform. The top plate and the positioning platform limit the two side surfaces of the pallet plate, and the two side plates position the other two side surfaces of the pallet plate. The clamping spring provides elastic force so that the two side plates can clamp the pallet plate, thereby preventing the pallet plate from moving on the lifting plate, thereby causing uneven stacking.

[0016] 3. The present invention pushes six color cartons onto the pallet plate at the same time through the push plate of the push plate, and the first layer on the pallet plate is covered with vertical color cartons. Then the side plate 2 is close to the side plate 1, and the lower part of the vertical color cartons first touches the shifting inclined plate, so that the color cartons rotate relatively counterclockwise on the conveyor belt, and then the color cartons contact the guide inclined plate along the conveyor belt. The guide inclined plate guides the color cartons, so that the color cartons run in a horizontal direction on the conveyor belt; the push plate pushes the three color cartons in the horizontal direction to the top of the first layer of color cartons at the same time; therefore, the purpose of stacking the color cartons in a horizontal and vertical alternating arrangement can be achieved, thereby improving the anti-dumping ability of the stacked color cartons.

[0017] 4. When the push plate of the present invention moves away from the pallet plate, the double-slope structure of the insert plate separates from the arc structure of the two middle support plates, and the tension spring provides tension to move the two side alignment plates toward the stacking pile. The two side alignment plates simultaneously contact the left and right sides of the stacking pile to clamp the left and right sides of the stacking pile neatly.

[0018] 5. After the colored cartons are stacked on the pallet board, the present invention starts the sliding motor to move the lifting mechanism toward the wedge block for unloading. The inclined structure on the wedge block contacts the lever, and the wedge block drives the lever and the side plate to move away from the stacking pile. Therefore, the side plate and the top plate can be separated from the pallet board, exposing the pallet board, making it easy to unload the pallet board and the stacking pile of colored cartons from the lifting plate.

[0019] 6. When the telescopic shaft of the displacement cylinder of the present invention contracts, the horizontal rod translates toward the direction of the frame, and the connecting rod drives the rocking arm to rotate counterclockwise synchronously, so the sliding column pushes the side plate 2 to move in the direction of the side plate 1. When the side plate 2 is close to the side plate 1, the rocking arm is perpendicular to the side plate 2, so the rocking arm and the sliding column form a pressure-maintaining state for the side plate 2. Therefore, when the side plate 2 is subjected to extrusion force, the rocking arm and the sliding column bear the main pressure, and the displacement cylinder is subjected to less pressure, thereby protecting the displacement cylinder.

DETAILED DESCRIPTION

[0036] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0037] Example: See Figure 1-15 Structural schematic diagram, the present invention provides the following technical solutions:

[0038] An automatic stacking device for colored paper boxes comprises a frame 1. A conveying mechanism 2 is arranged on the frame 1. The conveying mechanism 2 comprises a conveyor belt 201 for conveying colored paper boxes 3. The length of the colored paper boxes 3 is twice the width.

[0039] The conveying mechanism 2 also includes a transmission motor 202 and five rollers 203. The five rollers 203 are rotatably arranged on the frame 1, and the conveyor belt 201 is wound around the five rollers 203. The lowest roller 203 is connected to the rotating shaft of the transmission motor 202, and the transmission motor 202 is fixed on the frame 1. Specifically, the transmission motor 202 drives the lowest roller 203 to rotate, thereby driving the conveyor belt 201 to operate through friction, and placing the color paper box 3 from the loading end on the conveyor belt 201, thereby realizing the transmission of the color paper box 3.

[0040] A side plate 4 parallel to the conveyor belt 201 is provided on one side of the frame 1, and a guide inclined plate 5 is provided at the end of the side plate 4. A side plate 2 6 parallel to the side plate 4 is slidably provided on the other end of the frame 1, and two slide grooves 601 are provided on the side plate 2 6. A shifting inclined plate 7 is provided at the end of the side plate 2 6. The shifting inclined plate 7 is closer to the feeding end of the conveying mechanism 2 than the guide inclined plate 5.

[0041] Among them, the side plate 1 4 is set at an angle with the guide plate 5, and the right end of the guide plate 5 is inclined toward the side away from the side plate 2 6, and the side plate 2 6 is set at an angle with the displacement inclined plate 7, and the right end of the displacement inclined plate 7 is inclined toward the side away from the side plate 1 4.

[0042] Specifically, all the colored paper boxes 3 are placed on the conveyor belt 201 in a vertical direction (the length of the colored paper boxes 3 is perpendicular to the running direction of the conveyor belt 201). When the side plate 26 is away from the side plate 14, the guide plate 5 and the shifting inclined plate 7 do not work, and the colored paper boxes 3 are always transmitted on the conveyor belt 201 in a vertical direction; when the side plate 26 is close to the side plate 14, and the distance between the side plate 26 and the side plate 14 is slightly larger than the width of the colored paper boxes 3, the lower part of the vertical colored paper boxes 3 first touches the shifting inclined plate 7, so that the colored paper boxes 3 rotate relatively counterclockwise on the conveyor belt 201, and then the colored paper boxes 3 contact the guide plate 5 along the conveyor belt 201. The guide plate 5 guides the colored paper boxes 3, so that the colored paper boxes 3 enter between the side plate 14 and the side plate 26, so that the colored paper boxes 3 run on the conveyor belt 201 in a horizontal direction (the length of the colored paper boxes 3 is parallel to the running direction of the conveyor belt 201).

[0043] Two rocking arms 8 are rotatably provided on one side of the frame 1 close to the side plate 2 6, and sliding columns 9 are provided at the ends of the rocking arms 8. The two sliding columns 9 respectively form a sliding fit with the two slide grooves 601, and connecting rods 10 are fixedly provided under the rotating shaft of the rocking arms 8. The two connecting rods 10 are hinged with a flat rod 11 together, and a displacement cylinder 12 is provided at the end of the flat rod 11. The telescopic shaft end of the displacement cylinder 12 is hinged to the end of the flat rod 11, and the base of the displacement cylinder 12 is hinged to the side of the frame 1.

[0044] Specifically, when the telescopic shaft of the shifting cylinder 12 contracts, the horizontal rod 11 translates toward the direction of the frame 1, and at the same time the connecting rod 10 rotates counterclockwise, and the connecting rod 10 drives the rocking rod 8 to rotate counterclockwise synchronously, so the sliding column 9 pushes the side plate 2 6 to move toward the side plate 1 4. When the side plate 2 6 is close to the side plate 1 4, the rocking rod 8 is perpendicular to the side plate 2 6, so the rocking rod 8 and the sliding column 9 form a pressure-maintaining state for the side plate 2 6. When the side plate 2 6 is subjected to extrusion pressure, the rocking rod 8 and the sliding column 9 bear the main pressure, and the shifting cylinder 12 is subjected to less pressure, thereby protecting the shifting cylinder 12. When the telescopic shaft of the shifting cylinder 12 is extended, the side plate 2 6 moves away from the side plate 1 4 in the reverse process of the above principle, that is, the side plate 2 6 moves away from the side plate 1 4.

[0045] An attachment plate 13 is fixedly provided on one side of the frame 1 close to the side plate 4, and a push motor 14 is provided on the attachment plate 13. A push screw 15 is connected to the rotating shaft of the push motor 14. A slide seat 16 is slidably provided on the attachment plate 13, and the middle part of the slide seat 16 forms a threaded fit with the push screw 15. A connecting column 17 is vertically provided on the slide seat 16, and a push plate 18 is provided at the end of the connecting column 17. The push plate 18 includes a flat push plate 181 and a side baffle 182 which are perpendicular to each other. The flat push plate 181 is vertically connected to the end of the connecting column 17, and the side baffle 182 is perpendicular to the running direction of the conveyor belt 201.

[0046] Specifically, a transition plate 41 is provided on one side of the frame 1 close to the side plate 26. The transition plate 41 is flush with the upper edge of the side of the frame 1, and the transition plate 41 is flush with the surface of the conveyor belt 201. When the conveyor belt 201 brings the colored paper box 3 into contact with the side baffle 182, the side baffle 182 blocks the colored paper box 3 from moving. When the side baffle 182 blocks the six vertical colored paper boxes 3 from moving, the push motor 14 is started to drive the push screw 15 to rotate, and the push screw 15 drives the slide 16 to move, and the power is transmitted through the connecting column 17 to make the push plate 18 move toward the direction of the transition plate 41. Therefore, the flat push plate 181 of the push plate 18 pushes the six colored paper boxes 3 to move to the transition plate 41 at the same time; by the same principle, when the side baffle 182 blocks the movement of three horizontal colored paper boxes 3, the push motor 14 is started, and the flat push plate 181 pushes the three colored paper boxes 3 to move to the transition plate 41 at the same time.

[0047] A lifting mechanism 19 is provided on one side of the frame 1 close to the second side plate 6 . The lifting mechanism 19 includes a lifting seat 191 and a lifting plate 192 . A pallet plate 20 for stacking the colored paper boxes 3 is placed on the lifting plate 192 .

[0048] The lifting mechanism 19 further includes a side frame 193, a side frame 194 and a lifting hydraulic cylinder 195. The side frame 193 and the side frame 194 each include two side panels. Two cross bars are connected between the two side panels. The side frame 193 and the side frame 194 are cross-arranged. The side panels of the side frame 193 and the side edges of the side frame 194 are hinged in the middle. The lower cross bar of the side frame 193 is hinged to the lifting seat 191. The upper cross bar of the side frame 193 is slidably matched with the lifting plate 192. The lower cross bar of the side frame 194 is slidably matched with the lifting seat 191. The upper cross bar of the side frame 194 is hinged to the lifting plate 192. Then, the base of the lifting hydraulic cylinder 195 is hinged to the lower cross bar of the side frame 193, and the end of the telescopic shaft of the lifting hydraulic cylinder 195 is hinged to the lower cross bar of the side frame 194; specifically, when the telescopic shaft of the lifting hydraulic cylinder 195 is contracted, the lower cross bar of the side frame 194 moves along the lifting seat 191 toward the lower cross bar of the side frame 193, and due to the interaction between the side frame 193 and the side frame 194, the upper cross bars of the side frame 193 and the side frame 194 are synchronously raised, so that the lifting plate 192 can be translated upward; based on the above principle, when the telescopic shaft of the lifting hydraulic cylinder 195 is extended, the lifting plate 192 is translated downward.

[0049] The pallet plate 20 on the lifting plate 192 is made flush with the transition plate 41, and the side baffle 182 of the push plate 18 now pushes the six vertical colored paper boxes 3 onto the pallet plate 20. The first layer on the pallet plate 20 is covered with vertical colored paper boxes 3. Then the lifting plate 192 is lowered by the height of the colored paper boxes 3, and the side baffle 182 of the push plate 18 pushes the three horizontal colored paper boxes 3 to the top of the first layer of colored paper boxes 3. The colored paper boxes 3 are cyclically stacked on the pallet plate 20 in the above manner, so the purpose of stacking the colored paper boxes 3 in a horizontal and vertical alternating arrangement can be achieved, thereby improving the anti-dumping ability of the stacked colored paper boxes 3.

[0050] Taking into account that when the colored paper boxes 3 are stacked on the pallet board 20, since the colored paper boxes 3 slide on the transition plate 41 and the pallet board 20, the left and right sides of the stack on the pallet board 20 may not be aligned, a plug plate 21 is provided on the upper side of the push plate 181, and an alignment frame 22 is provided on the frame 1 and directly above the lifting mechanism 19. Two side slides 23 are symmetrically slidably provided in the alignment frame 22, and side alignment plates 24 for clamping the aligned colored paper boxes 3 are vertically provided on the side slides 23. Middle support plates 25 are provided on the side alignment plates 24, and tension springs 26 are connected between the two middle support plates 25; an arc structure is provided at the end of the middle support plate 25, and the end of the plug plate 21 is a double inclined surface structure for driving the arc structure of the middle support plate 25.

[0051] Specifically, when the push plate 181 moves toward the direction of the pallet plate 20, the double-sloped structure of the insert plate 21 contacts the arc structure of the two middle support plates 25, driving the middle support plate 25, the side alignment plate 24, and the side slide plate 23 to move toward the outside of the stacking pile, and the tension spring 26 is stretched, so that the push plate 181 can smoothly push the colored paper box 3 to the top of the pallet plate 20 for stacking; when the push plate 181 moves away from the pallet plate 20, the double-sloped structure of the insert plate 21 separates from the arc structure of the two middle support plates 25, and the tension spring 26 provides tension to move the two side alignment plates 24 toward the stacking pile, and the two side alignment plates 24 simultaneously contact the left and right sides of the stacking pile to clamp the left and right sides of the stacking pile neatly.

[0052] A sliding base 27 is provided directly below the lifting mechanism 19, and a sliding motor 28 is provided on the sliding base 27. A sliding screw 29 is connected to the end of the rotating shaft of the sliding motor 28, and the sliding base 27 forms a sliding fit with a lifting seat 191 of the lifting mechanism 19, and the lifting seat 191 forms a threaded fit with the sliding screw 29.

[0053] Specifically, the sliding motor 28 drives the sliding screw 29 to rotate, and the sliding screw 29 drives the lifting seat 191 to slide on the sliding base 27 .

[0054] Taking into account the need to automatically place the pallet plate 20 on the lifting plate 192 during continuous operation, a positioning platform 30 for positioning the pallet plate 20 is provided at the edge of the lifting plate 192 of the lifting mechanism 19, and two latches 31 are symmetrically slidably provided on the positioning platform 30, a latch spring 32 is connected between the two latches 31, the end of the latch 31 is a round head, and a positioning notch 301 is provided on the positioning platform 30 and at the round head of the latch 31.

[0055] A storage box 33 for storing the pallet plate 20 is provided above the sliding base 27. The four inner walls of the storage box 33 are provided with inner panels 34. The upper end of the inner panel 34 is an inclined structure. The outlet of the storage box 33 is located directly above the sliding base 27, and two sliding blocking rods 35 are provided at the outlet of the storage box 33 for parallel sliding. The end of the sliding blocking rod 35 close to the lifting mechanism 19 is a vertical support rod 351, and the other end of the sliding blocking rod 35 is connected to a joint plate 36.

[0056] Specifically, multiple pallet plates 20 are placed in the warehouse box 33, and the upper inclined surface structure of the inner plate 34 facilitates the placement of the pallet plates 20 in sequence. The blocking slide bar 35 blocks the pallet plates 20 from falling from the exit of the warehouse box 33, and the lifting mechanism 19 moves toward the direction of the warehouse box 33. The ends of the two latches 31 are respectively in contact with the vertical support rods 351 of the two blocking slide bars 35, so the blocking slide bars 35 and the joint plate 36 are pushed to move toward the outside of the warehouse box 33. The diameter of the vertical support rod 351 is smaller than the thickness of the inner plate 34. When the lifting plate 192 moves to just below the exit of the warehouse box 33, the blocking slide bar 35 no longer blocks the pallet plates 20, so the pallet plates 20 fall on the lifting plate 192, and the blocking slide bar 35 no longer moves, and the latch 31 slides on the positioning platform 30. The spring 32 is compressed, and the vertical support rod 351 of the sliding rod 35 smoothly enters the notch 301; the lifting mechanism 19 moves in the direction away from the warehouse box 33. Since the round head at the end of the latch 31 limits the vertical support rod 351, the sliding rod 35 moves simultaneously with the lifting mechanism 19. At the same time, the positioning platform 30 contacts the side of the lowest tray plate 20, and the positioning platform 30 moves synchronously with the lifting mechanism 19 with the lowest tray plate 20. When the closing plate 36 contacts the warehouse box 33, the sliding rod 35 no longer moves, the latch 31 slides on the positioning platform 30, and the vertical support rod 351 of the sliding rod 35 disengages from the notch 301, and the push screw 15 is re-located below the exit of the warehouse box 33 to prevent the remaining tray plates 20 from falling.

[0057] Taking into account that the positioning platform 30 only positions the side of the pallet plate 20, the pallet plate 20 may still move on the lifting plate 192 during the movement of the lifting mechanism 19 and during the stacking process, causing uneven stacking. Therefore, the lifting plate 192 of the lifting mechanism 19 is slidably provided with side plates 37 on both sides perpendicular to the positioning platform 30, and a top plate 371 is vertically provided at the end of the side plate 37. The upper surfaces of the side plates 37 and the top plate 371 and the edges close to the central axis of the lifting plate 192 are all inclined structures. A clamping spring 38 is connected between the side plate 37 and the lifting plate 192, and a lever 39 is provided under the side plate 37.

[0058] Specifically, the upper surface of the positioning platform 30 and the edges close to the side plates 37 are inclined structures. When the pallet plate 20 falls from the magazine box 33 to the lifting plate 192, the inclined structures of the side plates 37, the top plates 371 and the positioning platform 30 facilitate the pallet plate 20 to fall to the middle position of the side plates 37, the top plates 371 and the positioning platform 30. The top plates 371 and the positioning platform 30 limit the two side surfaces of the pallet plate 20, and the two side plates 37 position the other two side surfaces of the pallet plate 20. The clamping springs 38 provide elastic force so that the two side plates 37 can clamp the pallet plate 20.

[0059] Considering that after the colored paper boxes 3 are stacked on the pallet board 20, in order to facilitate the unloading of the pallet board 20 and the stack from the lifting plate 192, the side plates 37 and the top plates 371 need to be separated from the pallet board 20, so wedge blocks 40 for driving the lever 39 are provided on both sides of the sliding base 27. Specifically, the sliding motor 28 is started to move the lifting mechanism 19 in the direction of the wedge block 40, and the inclined surface structure on the wedge block 40 contacts the lever 39, and the wedge block 40 drives the lever 39 and the side plates 37 to move away from the stack, so that the side plates 37 and the top plates 371 can be separated from the pallet board 20.

[0060] Working principle: in the original state, there is no pallet plate 20 on the lifting plate 192 of the lifting mechanism 19, and multiple pallet plates 20 are placed in the warehouse box 33. The upper inclined surface structure of the inner plate 34 is convenient for placing the pallet plates 20 in sequence, and the blocking slide rod 35 blocks the pallet plates 20 from falling from the exit of the warehouse box 33; start the sliding motor 28, the sliding motor 28 drives the sliding screw 29 to rotate, and the sliding screw 29 drives the lifting seat 191 to slide on the sliding base 27, so that the lifting mechanism 19 moves toward the direction of the warehouse box 33, and the ends of the two latches 31 are respectively in contact with the vertical support rods 351 of the two blocking slide rods 35, so the blocking slide rod 35 and the joint plate 36 are pushed to move toward the outside of the warehouse box 33. The diameter of the vertical support rod 351 is smaller than the thickness of the inner plate 34. When the lifting plate 192 moves to the bottom of the exit of the warehouse box 33, the blocking slide rod 35 no longer blocks the pallet plate 20, and the blocking slide rod 35 no longer moves, and the latch 31 slides on the positioning platform 30, the latch spring 32 is compressed, and the vertical support rod 351 of the sliding rod 35 smoothly enters the notch 301; the upper surface of the positioning platform 30 and the edge close to the side plate 37 are an inclined structure. When the pallet plate 20 falls from the warehouse box 33 to the lifting plate 192, the inclined structure of the side plate 37, the top plate 371 and the positioning platform 30 facilitates the pallet plate 20 to fall to the middle position of the side plate 37, the top plate 371 and the positioning platform 30. The top plate 371 and the positioning platform 30 limit the two side surfaces of the pallet plate 20, and the two side plates 37 position the other two side surfaces of the pallet plate 20, and the clamping spring 38 provides elastic force, so that the two side plates 37 can clamp the pallet plate 20, so that the pallet plate 20 can be automatically placed on the lifting plate 192, and the pallet plate 20 can be prevented from moving on the lifting plate 192 to cause uneven stacking.

[0061] The lifting mechanism 19 is moved in the direction away from the warehouse box 33. Since the round head at the end of the latch 31 limits the vertical support rod 351, the sliding bar 35 moves simultaneously with the lifting mechanism 19. At the same time, the positioning platform 30 contacts the side of the lowest pallet plate 20, and the positioning platform 30 moves synchronously with the lifting mechanism 19 with the lowest pallet plate 20. When the closing plate 36 contacts the warehouse box 33, the sliding bar 35 no longer moves, the latch 31 slides on the positioning platform 30, and the vertical support rod 351 of the sliding bar 35 disengages from the notch 301, and the push screw 15 is re-located below the exit of the warehouse box 33 to prevent the remaining pallet plates 20 from falling, and the lifting mechanism 19 is moved to the bottom of the aligning frame 22, and the lifting hydraulic cylinder 195 of the lifting mechanism 19 is started to make the upper surface of the pallet plate 20 on the lifting plate 192 flush with the transition plate 41.

[0062] All the colored cartons 3 are placed on the feeding end of the conveyor belt 201 in a vertical direction in sequence, so that the telescopic shaft of the displacement cylinder 12 is extended. Even if the side plate 2 6 is away from the side plate 1 4, the guide inclined plate 5 and the displacement inclined plate 7 have no effect on the colored cartons 3. The colored cartons 3 are always transmitted on the conveyor belt 201 in a vertical direction. The conveyor belt 201 brings the vertical colored cartons 3 into contact with the side baffle 182. The side baffle 182 blocks the colored cartons 3 from moving. When the side baffle 182 blocks the movement of the six vertical colored cartons 3, the push motor 14 is started to drive the push motor 14 to push the colored cartons 3. The screw feed rod 15 rotates, and the push screw rod 15 drives the slide 16 to move, and transmits power through the connecting column 17, so that the push plate 18 moves in the direction of the transition plate 41, so the flat push plate 181 of the push plate 18 simultaneously pushes the six color paper boxes 3 to move to the transition plate 41 at the same time, and then pushes the six color paper boxes 3 onto the tray plate 20, and the first layer on the tray plate 20 is full of vertical color paper boxes 3, and then the lifting plate 192 is lowered by the height of the color paper boxes 3; when the telescopic shaft of the displacement cylinder 12 is contracted, the flat rod 11 is translated in the direction of the frame 1, and the connecting rod 10 rotates counterclockwise The connecting rod 10 drives the swing rod 8 to rotate counterclockwise synchronously, so the sliding column 9 pushes the side plate 2 6 to move in the direction of the side plate 1 4, so that the side plate 2 6 is close to the side plate 1 4, and the distance between the side plate 2 6 and the side plate 1 4 is slightly larger than the width of the color paper box 3. The lower part of the vertical color paper box 3 first touches the shifting inclined plate 7, so that the color paper box 3 rotates relatively counterclockwise on the conveyor belt 201, and then the color paper box 3 contacts the guide inclined plate 5 along the conveyor belt 201. The guide inclined plate 5 guides the color paper box 3, and the color paper box 3 enters the side plate 4 and the side plate The colored paper boxes 3 are made to run on the conveyor belt 201 in a horizontal direction between the two 6. When the side baffle 182 blocks the movement of the three horizontal colored paper boxes 3, the pushing motor 14 is started, and the flat push plate 181 pushes the three colored paper boxes 3 to move to the transition plate 41 at the same time, and then pushes the three horizontal colored paper boxes 3 to the top of the first layer of colored paper boxes 3; the colored paper boxes 3 are cyclically stacked on the pallet plate 20 in the above manner, so the purpose of stacking the colored paper boxes 3 in a horizontal and vertical alternating arrangement can be achieved, thereby providing the stacked colored paper boxes 3 with anti-dumping ability.

[0063] When the push plate 181 moves toward the direction of the pallet plate 20, the double-sloped structure of the insert plate 21 contacts the arc structure of the two middle support plates 25, driving the middle support plate 25, the side alignment plate 24, and the side slide plate 23 to move toward the outside of the stacking pile, and the tension spring 26 is stretched, so that the push plate 181 can smoothly push the colored paper box 3 to the top of the pallet plate 20 for stacking; when the push plate 181 moves in the direction away from the pallet plate 20, the double-sloped structure of the insert plate 21 separates from the arc structure of the two middle support plates 25, and the tension spring 26 provides tension to move the two side alignment plates 24 toward the stacking pile, and the two side alignment plates 24 contact the left and right sides of the stacking pile at the same time, clamping the left and right sides of the stacking pile neatly.

[0064] Finally, after the colored paper boxes 3 are stacked on the pallet plate 20, the sliding motor 28 is started to move the lifting mechanism 19 toward the wedge block 40 for unloading. The inclined surface structure on the wedge block 40 contacts the lever 39, and the wedge block 40 drives the lever 39 and the side plate 37 to move away from the stacking pile. Therefore, the side plate 37 and the top plate 371 can be separated from the pallet plate 20, exposing the pallet plate 20, making it easier to unload the pallet plate 20 and the stacking pile of colored paper boxes 3 from the lifting plate 192.

[0065] Repeat the above process to continuously stack the colored cartons 3.

[0066] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
