Description

Technical Field

[0001] The present invention relates to the field of conveying facilities, and particularly to a logistics transportation and handling device. Background Art

[0002] An automated stereoscopic warehouse is a warehouse system that uses high-rise shelves to store goods. With its advantages such as high efficiency, energy conservation, and information management, the automated stereoscopic warehouse plays an increasingly important role in modern logistics warehousing. With the continuous progress of technology and the continuous expansion of application scenarios, the automated stereoscopic warehouse will have a broader development prospect.

[0003] In an automated stereoscopic warehouse, a chain conveyor is often used to transport packaging bags containing a small amount of goods. However, during the actual transportation process, when the packaging bag containing goods is transported to the inclined section of the chain conveyor, due to the action of its inclined plane, the goods in the packaging bag will roll, resulting in its inability to be smoothly transported upward. At the same time, the rolling of the goods in the packaging bag will also cause the packaging bag to shift, resulting in phenomena such as the bag mouth of the packaging bag being pressed on the conveyor. When subsequent handling personnel carry out handling, it is not convenient to grab and carry the bag mouth of the packaging bag. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the background art and propose a logistics transportation and handling device.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows: A logistics transportation and handling device includes a chain conveyor. A bracket is fixedly installed on the chain plate of the chain conveyor. A connecting shaft is rotatably installed at the end of the bracket. An adjusting member is installed at the end of the connecting shaft. Two guide sleeves are symmetrically and slidably installed at the front of the adjusting member. V-shaped bag clips and V-shaped bag frames are respectively installed at the front ends of the two guide sleeves. An L-shaped frame is elastically installed at the lower end of the adjusting member. A concave pushing frame is fixedly installed at the upper end of the L-shaped frame. Inclined pushing frames are rotatably installed between the two ends of the concave pushing frame and the two guide sleeves. A lower wheel is connected to the rear end of the L-shaped frame. A reversing gear is coaxially inlaid on the outer surface of the connecting shaft. A pushing tooth plate is engaged with the rear part of the reversing gear. The pushing tooth plate is elastically connected to the bracket. An upper wheel is connected to the pushing tooth plate. A bag clamping lower rail and a reversing upper rail are respectively installed on the inclined section of the frame of the chain conveyor. Both ends of the bag clamping lower rail and the reversing upper rail are inclined. And the length of the bag clamping lower rail is shorter than that of the reversing upper rail. The reversing upper rail is located above the bag clamping lower rail. The upper wheel rolls on the reversing upper rail. The lower wheel rolls on the bag clamping lower rail.

[0006] Preferably, connecting frames are fixedly installed at the middle parts of the opposite ends of the V-shaped bag clip and the V-shaped bag frame respectively. The two connecting frames are fixed to the front ends of the two guide sleeves respectively. A convex cap extends from the rear end of the pushing toothed plate, and the upper wheel is installed at the end of the convex cap.

[0007] Preferably, an extending frame is fixedly installed at the upper edge of the rear end of the bracket. A groove rod is fixedly installed at the end of the extending frame. The convex cap is slidably installed on the outer surface of the groove rod. A main return spring is wound around the outer side of the groove rod. The upper end of the main return spring is fixed to the extending frame, and the lower end of the main return spring is fixed to the upper end of the convex cap.

[0008] Preferably, the adjusting member includes a bearing frame fixedly installed at the end of the connecting shaft. An adjusting threaded column is rotatably installed between the upper and lower end faces inside the bearing frame. The adjusting threaded column penetrates out from the upper end of the bearing frame. A threaded sleeve is screwed on the outer surface of the adjusting threaded column. A rod block is arranged in front of the bearing frame. The rod block is connected to the threaded sleeve. A square guide rod is penetrated and embedded in the front part of the rod block. The guide sleeve is slidably installed on the outer surface of the square guide rod.

[0009] Preferably, a frame rod is fixedly installed at the lower end of the rod block. The L-shaped frame is slidably installed on the outer surface of the frame rod. A second return spring is wound around the outer side of the frame rod. A convex ring is embedded on the outer surface of the frame rod. The upper end of the second return spring is fixed to the convex ring, and the lower end of the second return spring is fixed to the L-shaped frame.

[0010] Preferably, two guide ears symmetrically extend from the outer surface of the threaded sleeve. The guide ears penetrate out from both sides of the bearing frame. The guide ears are slidably matched with the bearing frame. Connecting blocks are fixedly installed at the ends of the two guide ears. The rod block is fixed between the two connecting blocks.

[0011] Preferably, a threaded seat is embedded at the rear end of the L-shaped frame. An adjusting threaded rod is screwed inside the threaded seat. The upper and lower ends of the adjusting threaded rod penetrate out from the upper and lower ends of the threaded seat. A wheel seat is rotatably installed at the lower end of the adjusting threaded rod. The lower wheel is installed inside the wheel seat.

[0012] Preferably, a guide plate is fixedly installed at the upper end of the wheel seat. The guide plate is located behind the adjusting threaded rod. A concave guide seat extends from the rear end of the threaded seat. The guide plate is slidably installed inside the concave guide seat. The lower end of the flipping upper rail and the lower end of the bag clamping lower rail are fixedly installed with a rail frame. The end of the rail frame is fixed to the frame of the chain conveyor.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When the packaging bag containing goods is about to be transported to the inclined section of the chain conveyor, the upper wheel just contacts the flipping upper rail and rolls along the inclined end of the flipping upper rail, driving the pushing tooth plate to move upward, further driving the flipping gear to rotate, causing the connecting shaft to flip, and making the V-shaped bag clips and V-shaped bag frames flip forward to both sides of the bag opening of the packaging bag. At this time, the lower wheel just contacts the bag clamping lower rail and rolls along the inclined end of the bag clamping lower rail to drive the concave pushing frame to move upward, further driving the inclined pushing frame to move, so as to push the guide sleeve, enabling the two guide sleeves to move towards each other, and thus making the V-shaped bag clips and V-shaped bag frames gather to clamp at the bag opening of the packaging bag. On the one hand, this ensures that the packaging bag can move upward smoothly when passing through the inclined section of the chain conveyor and will not roll downward, ensuring the normal operation of the transportation operation. On the other hand, it can ensure that the bag opening of the packaging bag is always in an upright state during transportation, effectively facilitating the subsequent handlers to grab and carry the bag opening.

[0014] 2. By rotating the adjusting threaded column, the threaded sleeve can be driven to move to adjust the height of the flipped V-shaped bag clips and V-shaped bag frames. At the same time, by rotating the adjusting threaded rod, the adjusting threaded rod can drive the lower wheel to move by using the thread between the threaded rod and the threaded seat to adapt to the height adjustment of the V-shaped bag clips and V-shaped bag frames, so that the heights of the V-shaped bag clips and V-shaped bag frames can adapt to bag openings of different heights to meet the transportation requirements.

[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0018] As Figures 1 - 8A logistics transportation and handling device shown in the figure includes a chain conveyor 1. A bracket 4 is fixedly installed on the chain of the chain conveyor 1. A connecting shaft 6 is rotatably installed at the end of the bracket 4. The bracket 4 serves to support the connecting shaft 6. An adjusting member is installed at the end of the connecting shaft 6. Two guide sleeves 35 are symmetrically and slidably installed at the front of the adjusting member. V-shaped bag clamps 31 and V-shaped bag frames 32 are respectively installed at the front ends of the two guide sleeves 35. The guide sleeves 35 serve to support the V-shaped bag clamps 31 and V-shaped bag frames 32. An L-shaped frame 11 is elastically installed at the lower end of the adjusting member. A concave push frame 10 is fixedly installed at the upper end of the L-shaped frame 11. Tilted push frames 33 are rotatably installed between the two ends of the concave push frame 10 and the two guide sleeves 35. The L-shaped frame 11 can drive the concave push frame 10 to move upward, and then drive the tilted push frames 33 to move, so as to push the guide sleeves 35, enabling the two guide sleeves 35 to move towards each other, so that the V-shaped bag clamps 31 and V-shaped bag frames 32 can gather and clamp at the bag mouth of the packaging bag 37. The rear end of the L-shaped frame 11 is connected to a lower wheel 23. A reversing gear 9 is coaxially inlaid on the outer surface of the connecting shaft 6. A push rack 7 is engaged with the rear part of the reversing gear 9. The push rack 7 is elastically connected to the bracket 4. The cooperation between the reversing gear 9 and the push rack 7 can drive the connecting shaft 6 to rotate, so that the V-shaped bag clamps 31 and V-shaped bag frames 32 can be flipped forward to both sides of the bag mouth of the packaging bag 37. An upper wheel 14 is connected to the push rack 7. A bag clamping lower rail 2 and a reversing upper rail 3 are respectively installed on the inclined section of the frame of the chain conveyor 1. Both ends of the bag clamping lower rail 2 and the reversing upper rail 3 are inclined. And the length of the bag clamping lower rail 2 is shorter than that of the reversing upper rail 3, which can ensure that before clamping, the V-shaped bag clamps 31 and V-shaped bag frames 32 are first flipped to both sides of the bag mouth of the packaging bag 37, and when resetting, it is ensured that after the V-shaped bag clamps 31 and V-shaped bag frames 32 release the clamping of the bag mouth, they are then flipped and reset. The reversing upper rail 3 is located above the bag clamping lower rail 2. The upper wheel 14 rolls on the reversing upper rail 3 and can roll along the inclined end of the reversing upper rail 3 to drive the push rack 7 to move. The lower wheel 23 rolls on the bag clamping lower rail 2 and can drive the L-shaped frame 11 to move upward by using the inclined end of the bag clamping lower rail 2.

[0019] Connecting frames 30 are fixedly installed at the middle parts of the opposite ends of the V-shaped bag clamps 31 and the V-shaped bag frames 32. The connecting frames 30 serve to connect and fix the V-shaped bag clamps 31 and the V-shaped bag frames 32. The two connecting frames 30 are respectively fixed to the front ends of the two guide sleeves 35. A convex cap 13 extends from the rear end of the push rack 7. The upper wheel 14 is installed at the end of the convex cap 13. The convex cap 13 serves to connect the upper wheel 14.

[0020] At the upper edge of the rear end of the support 4, an extension frame 8 is fixedly installed. At the end of the extension frame 8, a groove rod 16 is fixedly installed. The extension frame 8 functions to fix the groove rod 16. The convex cap 13 is slidably installed on the outer surface of the groove rod 16. A main return spring 12 is wound around the outside of the groove rod 16. The cooperation between the groove rod 16 and the convex cap 13 functions to guide the push tooth plate 7. The upper end of the main return spring 12 is fixed to the extension frame 8, and the lower end of the main return spring 12 is fixed to the upper end of the convex cap 13. The main return spring 12 can reset the moved push tooth plate 7, thereby causing the V-shaped bag clip 31 and the V-shaped bag frame 32 to flip backward and reset, exposing the upper part of the packaging bag 37 to avoid occlusion, so that subsequent handlers can grab the bag mouth of the packaging bag 37 and lift it for handling.

[0021] The adjusting member includes a bearing frame 24 fixedly installed at the end of the connecting shaft 6. Between the upper and lower end faces inside the bearing frame 24, an adjusting threaded column 25 is rotatably installed. The bearing frame 24 functions to bear the adjusting threaded column 25. The adjusting threaded column 25 passes through the upper end of the bearing frame 24. A threaded sleeve 26 is screwed tightly on the outer surface of the adjusting threaded column 25. The cooperation between the adjusting threaded column 25 and the threaded sleeve 26 can adjust the height of the flipped V-shaped bag clip 31 and V-shaped bag frame 32. In front of the bearing frame 24, a rod block 29 is provided. The rod block 29 is connected to the threaded sleeve 26. In the front part of the rod block 29, a square guide rod 34 is penetrated and embedded. The rod block 29 functions to connect the square guide rod 34. A guide sleeve 35 is slidably installed on the outer surface of the square guide rod 34. The square guide rod 34 functions to provide a straight sliding path for the guide sleeve 35.

[0022] At the lower end of the rod block 29, a frame rod 36 is fixedly installed. The L-shaped frame 11 is slidably installed on the outer surface of the frame rod 36. The frame rod 36 functions to guide the L-shaped frame 11. A second return spring 17 is wound around the outside of the frame rod 36. A convex ring 15 is embedded on the outer surface of the frame rod 36. The convex ring 15 functions to bear the second return spring 17. The upper end of the second return spring 17 is fixed to the convex ring 15, and the lower end of the second return spring 17 is fixed to the L-shaped frame 11. The second return spring 17 can push the L-shaped frame 11 to reset, thereby driving the V-shaped bag clip 31 and the V-shaped bag frame 32 to reset to release the clamping of the bag mouth of the packaging bag 37.

[0023] On the outer surface of the threaded sleeve 26, two guide ears 28 symmetrically extend. The guide ears 28 function to guide the threaded sleeve 26. The guide ears 28 pass through the two sides of the bearing frame 24. The guide ears 28 are slidably matched with the bearing frame 24. At the ends of both guide ears 28, connection blocks 27 are fixedly installed. The rod block 29 is fixed between the two connection blocks 27. The connection blocks 27 function to fix the rod block 29.

[0024] A threaded seat 18 is inlaid at the rear end of the L-shaped frame 11. An adjusting threaded rod 21 is screwed inside the threaded seat 18. The threaded seat 18 and the adjusting threaded rod 21 can adjust the position of the lower wheel 23 to adapt to the height adjustment of the V-shaped bag clip 31 and the V-shaped bag frame 32. After adjustment, the lower wheel 23 can still roll along the lower bag clamping rail 2. The upper and lower ends of the adjusting threaded rod 21 penetrate through the upper and lower ends of the threaded seat 18. A wheel seat 22 is rotatably installed at the lower end of the adjusting threaded rod 21. The lower wheel 23 is installed inside the wheel seat 22, and the wheel seat 22 serves to carry the lower wheel 23.

[0025] A guide plate 20 is fixedly installed at the upper end of the wheel seat 22. The guide plate 20 is located behind the adjusting threaded rod 21. A concave guide seat 19 extends from the rear end of the threaded seat 18. The guide plate 20 is slidably installed inside the concave guide seat 19. The guide plate 20 and the concave guide seat 19 serve to guide the wheel seat 22. The lower end of the flipping upper rail 3 is fixedly installed with a rail frame 5 at the lower end of the lower bag clamping rail 2. The end of the rail frame 5 is fixed to the frame of the chain conveyor 1. The rail frame 5 serves to support and fix the flipping upper rail 3 and the lower bag clamping rail 2.

[0026] During transportation, first rotate the adjusting screw column 25 to drive the movement of the threaded sleeve 26, so as to adjust the height of the inverted V-shaped bag clip 31 and the V-shaped bag frame 32. At the same time, rotate the adjusting screw rod 21, and let the adjusting screw rod 21 drive the lower wheel 23 to move under the thread between the adjusting screw rod 21 and the threaded seat 18, so as to adapt to the height adjustment of the V-shaped bag clip 31 and the V-shaped bag frame 32, so that the heights of the V-shaped bag clip 31 and the V-shaped bag frame 32 can adapt to the bag mouth height of the packaging bag 37 to be transported. Then place the packaging bag 37 filled with goods upright on the chain conveyor 1 for transportation. At this time, the packaging bag 37 is close to the bracket 4. When the packaging bag 37 filled with goods is about to be transported to the inclined section of the chain conveyor 1, the upper wheel 14 just contacts the inverted upper rail 3 and rolls along the inclined end of the inverted upper rail 3, driving the push tooth plate 7 to move upward, and then driving the inverted gear 9 to rotate, so that the connecting shaft 6 is inverted, and the V-shaped bag clip 31 and the V-shaped bag frame 32 are flipped forward to both sides of the bag mouth of the packaging bag 37. At this time, the lower wheel 23 just contacts the bag clamping lower rail 2 and rolls along the inclined end of the bag clamping lower rail 2, so as to drive the concave push frame 10 to move upward, and then drive the inclined push frame 33 to move, so as to push the guide sleeve 35, so that the two guide sleeves 35 can move towards each other, so that the V-shaped bag clip 31 and the V-shaped bag frame 32 are gathered to clamp at the bag mouth of the packaging bag 37, so that the bag mouth of the packaging bag 37 can pass through the inclined section of the chain conveyor 1 smoothly in an upright state. When passing through the inclined section of the chain conveyor 1, when the upper wheel 14 is about to separate from the inverted upper rail 3 and the lower wheel 23 is about to separate from the bag clamping lower rail 2, the second reset spring 17 will first gradually recover its deformation, so that the V-shaped bag clip 31 and the V-shaped bag frame 32 are reset to loosen the clamping of the bag mouth of the packaging bag 37. Then the main reset spring 12 will gradually recover its deformation, so that the V-shaped bag clip 31 and the V-shaped bag frame 32 are flipped backward and reset, so that the upper part of the packaging bag 37 is exposed to avoid shielding, so as to facilitate the subsequent handling personnel to grab the bag mouth of the packaging bag 37 and lift it for handling.
