Description

Technical Field

[0001] The invention relates to the field of logistics, and in particular to a pallet reversing device. Background Art

[0002] In the logistics system, the directions of some pallets entering the cargo port and the shelf may be different, which generally requires a rotating table, a transfer machine, a chain machine, a roller machine and other equipment to complete the reversing of the pallet. The patent with application number CN202023028918.7 discloses a new heavy-load lifting and reversing conveying device. Although the new heavy-load lifting and reversing conveying device can lift and reverse the goods on it, it also has the following disadvantages during use: 1) The device cannot rotate the goods, and thus cannot adjust the angle at which the goods enter the shelf; 2) The lifting device of the device is arranged at the bottom end of the chain conveying mechanism, so when the lifting device lifts the chain conveying mechanism, the chain on the chain conveying mechanism is subjected to a large instantaneous impact force of the goods at the moment of lifting, which is relatively narrow and not so rigid. The chain is easily damaged, so there is an urgent need for a logistics conveying device that can integrate rotation, lifting and transfer and can well protect the chain on the chain conveying mechanism.

[0016] (III) Beneficial effects

[0017] 1. The present invention integrates rotation, lifting and transplanting of the pallet reversing device by arranging a rotating table, a chain conveying mechanism, a lifting mechanism and a roller conveying mechanism, which greatly saves space and cost and improves efficiency. In addition, by arranging the lifting mechanism below the roller conveying mechanism, the chain conveying mechanism is well protected by the process of lifting and lowering the goods by lifting and lowering the roller conveying mechanism, thereby ensuring the stability of the device during use and increasing the service life of the device.

[0018] 2. The present invention provides the grooves, rotating rods and rollers. When the goods are transported by rollers, the rollers extending out of the grooves can better transport the goods. Especially for heavy goods, when the rollers rotate, each row of rollers pushes the goods forward. This transport mode can not only effectively transport the goods forward, but also greatly improve the transport efficiency of the goods. When the goods are transported by chains, the rollers can not only support the goods well, but also effectively relieve the load-bearing of the two second chains, thus protecting the second chains well. In addition, when the second chains transport the goods, the rollers will rotate accordingly, thus assisting the transport of the goods. This not only increases the transmission efficiency of the second chains, but also further protects the second chains well.

[0019] 3. The present invention configures the roller to be composed of a first fixed layer, a skeleton layer, a second fixed layer, metal balls, a shock-resistant layer and a third fixed layer. The roller of this structure is not only firm and stable in structure, but also has a good shock-absorbing effect. When the roller rotates, the metal balls between the first fixed layer and the second fixed layer will gather in the direction of rotation, thereby causing the overall center of gravity of the roller to deviate in the direction of rotation, thereby playing a role in assisting the rotation and further improving the transmission efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The present invention provides a technical solution: a pallet reversing device, comprising a base frame 1, a rotating mechanism 2 is provided on the base frame 1, a rotating table 3 is connected to the rotating mechanism 2, a first support frame 4 and a second support frame 5 are fixed on the rotating table 3, a chain conveying mechanism 6 is provided on the first support frame 4, a lifting mechanism 7 is provided on the second support frame 5, the lifting mechanism 7 is connected to a lifting frame 8, and a roller conveying mechanism 9 is provided on the lifting frame 8. When working, the first choice of goods is transmitted to the pallet reversing device, at this time, the roller conveying mechanism 9 is in a low position, and the goods are transmitted to the left end of the pallet reversing device through other transmission mechanisms, and then the goods are transmitted to the middle position of the device through the chain conveying mechanism 6, and then the goods are rotated at a corresponding angle according to the needs of the goods inlet, and then the lifting mechanism 7 is started to lift the lifting frame 8, and then the roller conveying mechanism 9 on the lifting frame 8 is lifted upward until the goods on the chain conveying mechanism 6 are lifted to completely separate from the chain conveying mechanism 6, and then the roller conveying mechanism 9 transports the goods to a designated location (shelf or transmission line). The present invention arranges a rotating table 3, a chain conveying mechanism 6, a lifting mechanism 7 and a roller conveying mechanism 9, so that the pallet reversing device integrates rotation, lifting and transplanting, which greatly saves space and cost, and also improves efficiency. In addition, by arranging the lifting mechanism 7 below the roller conveying mechanism 9, the goods are lifted and lowered by lifting and lowering the roller conveying mechanism 9. Compared with the method of lifting and lowering the chain conveying mechanism 9 in the background technology, the method in the present application can well protect the chain conveying mechanism 6, ensure the stability of the equipment during use, and at the same time increase the service life of the equipment.

[0031] The rotating mechanism 2 includes a first motor 10 fixed on the base frame 1, and a first bevel gear and a second bevel gear are connected to the output shaft of the first motor 10. The upper end of the connecting shaft 11 is fixed at the center position of the second bevel gear, and a gear 12 is fixed to the lower end of the connecting shaft 11. The gear 12 is meshed with a toothed disc 13, and the toothed disc 13 is fixed on the bottom surface of the rotating table 3. When the goods need to be rotated, the first motor 10 is started to drive the rotation of the first bevel gear fixed on its output shaft, and then drive the rotation of the second bevel gear meshed with the first bevel gear, wherein the second bevel gear is perpendicular to the first bevel gear, and then drives the connecting shaft 11 to rotate, and then drives the gear 12 to rotate, and then drives the toothed disc 13 to rotate, and then drives the rotating table 3 to rotate.

[0032] The chain conveying mechanism 6 includes a second motor 14 fixed to the side of the first supporting frame 4, a first sprocket is fixed on the output shaft of the second motor 14, the first sprocket is connected to the second sprocket 16 through the first chain 15, a transmission shaft 17 is fixed through the center position of the second sprocket 16, a third sprocket 18 is fixed at both ends of the transmission shaft 17, the third sprocket 18 is connected to the fourth sprocket 20 through the second chain 19, and the front and rear sides of the second chain 19 are provided with fixed plates 21, the fourth sprocket 20 is rotatably connected to the left end portions of the two fixed plates 21, and the third sprocket 18 is rotatably connected to the right ends of the two fixed plates 21. When it is necessary to transport the goods on the chain conveying mechanism 6, first the second motor 14 is started, and its output shaft drives the first sprocket to rotate, and then drives the second sprocket 16 to rotate through the first chain 15, and then drives the transmission shaft 17 to rotate, and then drives the third sprocket 18 to rotate, and then drives the second chain 19 and the fourth sprocket 20 to rotate, and finally the goods on the second chain 19 are transported.

[0033] The lifting mechanism 7 includes a third motor 22 fixed on the second support frame 5, and a fifth sprocket 23 and a sixth sprocket 24 are fixed on the output shaft of the third motor 22. The fifth sprocket 23 is connected to the seventh sprocket 26 through a third chain 25, and the sixth sprocket 24 is connected to the eighth sprocket through a fourth chain 27. The center positions of the seventh sprocket 26 and the eighth sprocket are both penetrated and fixed with a rotating shaft 28, and both ends of the rotating shaft 28 are fixed with eccentric wheels 29, and the eccentric wheel 29 is connected to the lifting frame 8. A connecting seat 30 is provided near the inner end of the eccentric wheel 29, and the connecting seat 30 is fixed on the second support frame 5 and is rotatably connected to the rotating shaft 28. When it is necessary to lift the goods, the third motor 22 is started first, and its output shaft drives the fifth sprocket 23 and the sixth sprocket 24 to rotate, thereby driving the seventh sprocket 26 and the eighth sprocket to rotate, thereby driving the rotating shaft 28 to rotate, and then driving the eccentric wheel 29 to rotate, thereby causing the lifting frame 8 to rise or fall.

[0034] The roller conveying mechanism 9 includes a plurality of rollers 31 fixed on the lifting frame 8, and a roller driving mechanism 32 is provided on the roller 31. The roller 31 includes a rotating shaft 33 rotatably connected to the lifting frame 8, and a roller body 34 is fixed on the rotating shaft 33. A plurality of grooves 35 are opened on the roller body 34, and a rotating rod 36 is rotatably connected in the groove 35. A roller 37 is fixed on the rotating rod 36, and the outer end of the roller 37 extends out of the groove 35. The rotating rod 36 is perpendicular to the rotating shaft 33. When it is necessary to transport the goods on the roller conveying mechanism 9, the roller driving mechanism 32 is started first, wherein the roller driving mechanism 32 belongs to the prior art and will not be described in detail here, and includes a driving motor and a transmission chain arranged between adjacent rollers. The driving mechanism 32 drives the roller 31 arranged on the lifting frame 8 to rotate, and then the goods thereon are transported. The grooves 35 on the roller body 34 are evenly arranged into several rows, and the distances between adjacent grooves 35 in each row are equal. Through the arrangement of the grooves 35, the rotating rods 36 and the rollers 37, when the goods are conveyed by the rollers, the rollers 37 extending out of the grooves 35 can better convey the goods, especially for heavy goods. Because when the heavy goods are conveyed by the rollers, the rollers often idle and fail to convey the goods effectively, resulting in low efficiency of the conveyance and even failure to convey the heavy goods. Therefore, through the arrangement of the rollers 31 of this structure, when conveying the heavy goods, the rollers 31 are rotated, and the goods are pushed forward by each row of rollers 37. This conveying method is not only effective for the goods ( Especially heavy objects) can be effectively transmitted forward, and the transmission efficiency of the goods is greatly improved; when the goods are chain-transmitted, the roller conveyor mechanism 9 descends until the top of the roller 37 thereon is flush with the upper surface of the second chain 19, so that when the two second chains 19 transmit the goods thereon, the roller 37 can not only provide good support for the goods (especially heavy objects), but also effectively alleviate the load-bearing capacity of the two second chains 19, and provide good protection for the second chains 19. In addition, when the second chain 19 transmits the goods, the roller 37 will rotate accordingly, thereby providing auxiliary transmission for the goods, which not only increases the transmission efficiency of the second chain 19, but also further provides good protection for the second chain 19.

[0035] The roller 37 includes a first fixing layer 38 fixed to the rotating rod 36, the first fixing layer 38 is fixed with a second fixing layer 40 through a skeleton layer 39, a plurality of metal balls 41 are arranged between the second fixing layer 40 and the first fixing layer 38, an anti-vibration layer 42 is fixed to the outside of the second fixing layer 40, and a third fixing layer 43 is fixed to the outside of the anti-vibration layer 42. The roller 37 is arranged with this structure, and not only is the structure firm and stable, but also can play a good shock absorbing role. When the roller 37 rotates (including two rotation modes, rotating with the roller 31 and rotating with the rotating rod 36), the metal balls 41 between the first fixing layer 38 and the second fixing layer 40 will gather in the direction of rotation, thereby making the overall center of gravity of the roller 37 deviate in the direction of rotation, thereby playing a role in assisting the rotation and further improving the transmission efficiency. In order to reduce noise, a sound insulation layer can be arranged on the surface of the roller 37.

[0036] The material of the shockproof layer 42 is rubber or silicone, and this configuration has a good shockproof and pressure-reducing effect.

[0037] The metal balls 41 fill three quarters of the space between the first fixed layer 38 and the second fixed layer 40 . This number of metal balls 41 can not only shift the center of gravity of the roller 37 , but also cause the force of the shift to be relatively large.

[0038] A guide frame 44 is provided directly in front of the chain conveying mechanism 6, wherein the guide frame 44 is provided with guide rollers, which play a good role in guiding and assisting transmission.

[0039] An annular block 45 is fixed on the bottom surface of the rotating table 3 , and four guide wheel structures 46 are evenly distributed below the annular block 45 . This arrangement not only provides good support for the rotating table 3 , but also assists the rotating table 3 in rotating.

[0040] Working principle: When working, the first cargo is transferred to the pallet reversing device. At this time, the roller conveyor mechanism 9 is in a low position. The cargo is transferred to the left end of the pallet reversing device through other transmission mechanisms, and then the cargo is transferred to the middle position of the device through the chain conveyor mechanism 6. Then, the cargo is rotated at a corresponding angle according to the needs of the cargo entrance. Then, the lifting mechanism 7 is started to lift the lifting frame 8, and then the roller conveyor mechanism 9 on the lifting frame 8 is lifted upward until the cargo on the chain conveyor mechanism 6 is lifted and completely separated from the chain conveyor mechanism 6. Then, the roller conveyor mechanism 9 transports the cargo to the designated location (shelf or transmission line). The present invention arranges a rotating table 3, a chain conveying mechanism 6, a lifting mechanism 7 and a roller conveying mechanism 9, so that the pallet reversing device integrates rotation, lifting and transplanting, which greatly saves space and cost, and also improves efficiency. In addition, by arranging the lifting mechanism 7 below the roller conveying mechanism 9, the goods are lifted and lowered by lifting and lowering the roller conveying mechanism 9. Compared with the method of lifting and lowering the chain conveying mechanism 9 in the background technology, the method in the present application can well protect the chain conveying mechanism 6, ensure the stability of the equipment during use, and at the same time increase the service life of the equipment.
