Description

Technical Field

[0001] The present invention belongs to the technical field of conveying systems, and in particular relates to a multi-directional conveying system and method. Background Art

[0002] A conveyor system is a system used to automatically move materials, goods, or products along a specific path. It is widely used in various industrial and commercial settings to improve production efficiency, reduce labor costs, and optimize logistics processes. There are many types of conveyor systems, each with its own specific applications and functions. Common conveyor systems include belt conveyors, roller conveyors, chain conveyors, and pneumatic conveyors. Roller conveyors consist of a series of parallel rollers on which materials are placed and moved by the rotation of the rollers. This system is suitable for applications that require precise control of material position and velocity.

[0003] Authorization publication number "CN114803242B" records "a material conveying system, including a material conveying line and a conveying track, wherein a plurality of conveying ports are provided on the material conveying line adjacent to the conveying track, and further comprising: at least one conveying device, which is slidably arranged on the conveying track, and is used to align with the plurality of conveying ports for material storage and retrieval, the conveying device includes a conveying trolley, a two-way telescopic mechanism arranged on the conveying trolley, and a loading platform arranged on the two-way telescopic mechanism, the telescopic direction of the two-way telescopic mechanism is consistent with the extension direction of the conveying track, and drives the loading platform to align with the conveying port; a positioning device, which is used to position the loading platform so that the loading platform and the conveying port remain relatively stationary during the material storage and retrieval process; when the loading platform is aligned with the conveying port for storing and retrieving materials, the conveying trolley continues to run on the conveying track. The material conveying system and control method provided by the present invention can realize non-stop operation during the loading and unloading process, thereby improving efficiency."

[0004] By adopting the technical solution of the above patent, when the loading platform is aligned with the material delivery port, the conveyor trolley continues to run. The positioning device allows the loading platform and the delivery port to remain relatively stationary during the continued operation of the conveyor trolley to complete the storage and retrieval of goods. The conveyor trolley does not need to stop to complete the storage and retrieval of materials, which greatly reduces the time consumed in material storage and retrieval and improves work efficiency. In the existing logistics conveying system, when two conveyor belts are horizontally staggered, the reversing flow and conveying of palletized goods are carried out with the help of a chain conveyor and a lifting and transferring machine. The two devices need to be used in a complex matching manner to divert and redirect the palletized goods. The purchase and use of chain conveyors and lifting and transferring machines increases the equipment purchase cost of the enterprise. For this reason, we propose a multi-directional conveying system and method. Summary of the Invention

[0025] An application method of a multi-directional conveying system comprises the following steps:

[0026] S1. Tighten:

[0027] Before the horizontal feeding process, the two second electric push rods are powered on and started, the output end of one second electric push rod contracts, and the output end of the other second electric push rod extends, so that the rack moves horizontally, and the rack engages with multiple rotating gears, and the multiple rotating gears drive multiple left and right rotating screws to rotate, and the multiple left and right rotating screws push the multiple tensioning blocks to move closer together by sliding with the multiple tensioning blocks. At the same time, the multiple guide rods guide the movement of the multiple tensioning blocks by sliding with the multiple tensioning blocks, so that the multiple tensioning blocks are opposite to each other in pairs, squeezing the upper and lower chains of the torsion transmission chain close to each other, preventing the torsion transmission chain from falling off, and strengthening the tension of the torsion transmission chain;

[0028] S2, Horizontal feeding:

[0029] After tensioning, power is turned on to start the two first electric push rods, the output ends of the two first electric push rods extend, the two first electric push rods push the two lower connecting rods, and the two lower connecting rods drive the two deflection plates to move in an arc around the L-shaped frame to the top of the L-shaped frame. At the same time, the multiple deflection plates are driven to move to the top of the L-shaped frame through the connection action of the synchronous frame, so that the multiple deflection plates are parallel to the fixed baffle to prevent the pallet cargo between the L-shaped frame and the hollow frame from falling off. The servo motor is powered on and started, and the output end of the servo motor drives a first sprocket to rotate, and the first sprocket drives the torsion transmission chain to rotate, and the torsion transmission chain then pulls the remaining first sprockets to rotate, and then the multiple first sprockets synchronously drive the multiple conveyor rollers to rotate, and the multiple conveyor rollers push the pallet cargo on the upper side of the multiple conveyor rollers to move laterally through rotation, thereby realizing lateral movement of the pallet cargo;

[0030] S3, Mode Switching:

[0031] When it is necessary to switch the pallet cargo from horizontal feeding to vertical receiving, the two first electric push rods are powered on and started, and the output ends of the two first electric push rods are retracted, and the output ends of the two first electric push rods pull the two lower connecting rods to deflect, and the two lower connecting rods pull the two deflection plates to move in an arc to one side of the L-shaped frame through deflection, and the two deflection plates are connected by the synchronous frame so that multiple deflection plates move to one side of the L-shaped frame, and multiple deflection plates are parallel to one side of the L-shaped frame, and the tops of multiple deflection plates correspond horizontally to the top of the L-shaped frame. At the same time, the two third electric push rods are powered on and started, and the output ends of the two third electric push rods push multiple switching bends The plate deflects with two rotating shafts as the axis, and multiple rollers lift multiple conveyor racks by rolling with multiple main rails, so that multiple wheel grooves, multiple sets of material transmission chains and drive components are lifted. Multiple rollers roll with multiple auxiliary rails to lower the L-shaped rack and the hollow rack, so that multiple conveyor rollers are lowered. Finally, multiple sets of material transmission chains are horizontally aligned with the top of the hollow rack, which facilitates the movement of palletized goods from one side of the hollow rack to between the L-shaped rack and the hollow rack. Conversely, when switching from longitudinal material connection to transverse material feeding, multiple conveyor rollers are lifted and multiple sets of material transmission chains are lowered to realize the mode switching between transverse material feeding and longitudinal material connection.

[0032] S4, longitudinal material connection:

[0033] When the mode switching is completed, the dual-axis motor is powered on and started, and the output end of the dual-axis motor drives the output shaft to rotate. The output shaft drives the multiple second sprockets located at the bottom to rotate through rotation, and the multiple second sprockets at the bottom drive the multiple sets of material transmission chains to rotate, so that the multiple sets of material transmission chains rotate around the circumferential surfaces of the multiple second sprockets on the multiple conveyor racks. The multiple sets of material transmission chains drive the pallet goods to move longitudinally, which is convenient for horizontal feeding. At the same time, when the pallet goods enter between the L-shaped rack and the hollow rack from one side of the hollow rack, the fixed baffle is used to block the pallet goods to prevent the pallet goods from falling longitudinally outside the L-shaped rack and the hollow rack, thereby realizing longitudinal material connection of the pallet goods;

[0034] S5, protective tray:

[0035] When the pallet is transported longitudinally, the output end of the drive motor is started to rotate, and one of the second synchronous wheels is driven to rotate through the rotation of the output end of the drive motor, and the bidirectional screw on one side is driven to rotate through the transmission cooperation of the second synchronous wheel and the second synchronous belt, and then the two bidirectional screws are rotated at the same time through the transmission cooperation of the first synchronous wheel and the first synchronous belt. When the bidirectional screw rotates forward, the threaded barrels on the front and rear sides move inward on the surface of the bidirectional screw at the same time, and the two cross plates are driven to move inward at the same time through the movement of the threaded barrel, and the mounting frame and multiple guide wheels are driven inward by the movement of the cross plate. When the cross plate moves inward until it contacts the pallet, the drive motor can be turned off, and the extension end of the cylinder is started to extend, and the extension end of the cylinder pushes the mounting frame and multiple guide wheels to move upward. The movement of multiple guide wheels makes it easy to correspond to the position of the pallet, thereby playing a protective effect during the longitudinal transportation of the pallet to prevent the pallet from falling.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. In this solution, multiple rollers, auxiliary rails, and main rails work together to adjust the height of multiple conveyor rollers and material transmission chains. Without the help of chain conveyors and lifting and transferring machines, a one-time synchronous switching mode is achieved through a swing assembly, simplifying the diversion and rerouting of palletized cargo. This not only ensures the rapid and effective switching of palletized cargo diversion and rerouting, but also reduces the company's procurement costs.

[0038] 2. In this solution, when it is necessary to rotate multiple sets of material transmission chains and move the pallet cargo longitudinally through the multiple sets of material transmission chains, the dual-axis motor is powered on and the output end of the dual-axis motor drives the two output shafts to rotate, the two output shafts drive multiple second sprockets to rotate, and the multiple second sprockets drive the multiple sets of material transmission chains to rotate. The multiple sets of material transmission chains move the pallet cargo longitudinally through rotation, and adjust the pallet cargo between the L-shaped frame and the hollow frame to avoid a large amount of friction caused by the pallet cargo fitting against the inner wall of the L-shaped frame and the hollow frame, and to avoid the pallet cargo from slowing down in the lateral movement between the L-shaped frame and the hollow frame, thereby improving the efficiency of lateral material movement.

[0039] 3. In this solution, the outer limit bar is used to limit the maximum swing angle of one side of the multiple switching bent plates, and the inner limit bar limits the maximum swing angle of the other side. The accommodating openings on the outer limit bar and the inner limit bar correspond to the multiple switching bent plates, effectively limiting the maximum deflection angle of the swing of the multiple switching bent plates, and then realizing the control of the upper and lower limit range of the height of the multiple conveying rollers and material transmission chains during the lifting process, which is convenient for docking with other components in the conveying system.

[0040] 4. In this solution, when multiple conveyor rollers need to rotate synchronously, power is turned on to start the two second electric push rods, the output end of one second electric push rod contracts, and the output end of the other second electric push rod extends, so that the rack moves laterally. The rack engages with multiple rotating gears, and the multiple rotating gears drive multiple left-hand screws to rotate. The multiple left-hand screws push the multiple tensioning blocks to move closer together by sliding with the multiple tensioning blocks. At the same time, the multiple guide rods guide the movement of the multiple tensioning blocks by sliding with the multiple tensioning blocks, so that the multiple tensioning blocks are opposite to each other in pairs, squeezing the upper and lower chains of the torsion transmission chain closer together, tightening the torsion transmission chain, and making the multiple conveyor rollers rotate synchronously through the tightening of the torsion transmission chain, thereby improving the efficiency of the synchronous rotation of the multiple conveyor rollers. When the multiple left-hand screws push the multiple tensioning blocks to move away from each other in pairs by sliding with the multiple tensioning blocks, the torsion transmission chain loosens. At this time, the servo motor can only drive one conveyor roller when it is powered on, so that a single conveyor roller can rotate, thereby stopping the movement of a single pallet material in actual use.

[0041] When the loaders are at the top of the L-shaped frame, the loaders are parallel to each other and the top of the L-shaped frame is horizontally aligned with the top of the L-shaped frame, so that the loaders can move freely in and out of the L-shaped frame.

[0042] 6. In this solution, when the pallet is transported longitudinally, the output end of the drive motor is started to rotate, and one of the second synchronous wheels is driven to rotate by the rotation of the output end of the drive motor, and the bidirectional screw on one side is driven to rotate by the transmission cooperation of the second synchronous wheel and the second synchronous belt, and then the two bidirectional screws are rotated simultaneously by the transmission cooperation of the first synchronous wheel and the first synchronous belt. When the bidirectional screw rotates forward, the threaded barrels on the front and rear sides move inward on the surface of the bidirectional screw at the same time, and the two cross plates are driven to move inward at the same time by the movement of the threaded barrel, and the mounting frame and multiple guide wheels are driven to move inward by the movement of the cross plate. When the cross plate moves inward until it contacts the pallet, the drive motor can be turned off, and the extension end of the cylinder is started to extend, and the extension end of the cylinder pushes the mounting frame and multiple guide wheels to move upward. The movement of multiple guide wheels makes it easy to correspond to the position of the pallet, thereby playing a protective effect during the longitudinal transportation of the pallet to prevent the pallet from falling.

At the same time, the multiple guide rods 10 guide the movement of the multiple tensioning blocks 8 by sliding with the multiple tensioning blocks 8, so that the multiple tensioning blocks 8 are opposite to each other in pairs, squeezing the upper and lower chains of the torsion transmission chain 6 close to each other, preventing the torsion transmission chain 6 from falling off, and strengthening the tension of the torsion transmission chain 6;

[0100] S2, Horizontal feeding:

[0101] After being tightened, the two first electric push rods 30 are powered on and the output ends of the two first electric push rods 30 are extended, and the two first electric push rods 30 push the two lower connecting rods 35, and the two lower connecting rods 35 drive the two deflection plates 31 to move in an arc around the L-shaped frame 4 to the top of the L-shaped frame 4. At the same time, the multiple deflection plates 31 are driven to move to the top of the L-shaped frame 4 through the connection action of the synchronous frame 36, so that the multiple deflection plates 31 are parallel to the fixed baffle 40, so as to prevent the pallet cargo between the L-shaped frame 4 and the hollow frame 5 from falling off, and the servo motor 16 is powered on and started, and the output end of the servo motor 16 drives a first sprocket 7 to rotate, and the first sprocket 7 drives the torsion transmission chain 6 to rotate, and the torsion transmission chain 6 then pulls the remaining first sprockets 7 to rotate, and then the multiple first sprockets 7 synchronously drive the multiple conveyor rollers 2 to rotate, and the multiple conveyor rollers 2 push the pallet cargo on the upper side of the multiple conveyor rollers 2 to move laterally through rotation, thereby realizing the lateral movement of the pallet cargo;

[0102] S3, Mode Switching:

[0103] When it is necessary to switch the pallet cargo from horizontal feeding to longitudinal receiving, the two first electric push rods 30 are powered on and started, and the output ends of the two first electric push rods 30 are retracted. The output ends of the two first electric push rods 30 pull the two lower connecting rods 35 to deflect, and the two lower connecting rods 35 pull the two deflection plates 31 to move in an arc to one side of the L-shaped frame 4 through deflection, and the two deflection plates 31 are connected by the synchronous frame 36 so that multiple deflection plates 31 move to one side of the L-shaped frame 4, multiple deflection plates 31 are parallel to one side of the L-shaped frame 4, and the tops of multiple deflection plates 31 are horizontally corresponding to the top of the L-shaped frame 4.

Finally, the multiple sets of material transmission chains 3 are horizontally aligned with the top of the hollow rack 5, which facilitates the movement of palletized goods from one side of the hollow rack 5 to between the L-shaped rack 4 and the hollow rack 5. Conversely, when switching from longitudinal material connection to transverse material feeding, the multiple conveyor rollers 2 are lifted and the multiple sets of material transmission chains 3 are lowered to realize the mode switching between transverse material feeding and longitudinal material connection;

[0104] S4, longitudinal material connection:

[0105] After the mode switching is completed, the dual-axis motor 26 is powered on and started. The output end of the dual-axis motor 26 drives the output shaft 27 to rotate. The output shaft 27 drives the multiple second sprockets 24 at the bottom to rotate through rotation. The multiple second sprockets 24 at the bottom drive the multiple groups of material transmission chains 3 to rotate, so that the multiple groups of material transmission chains 3 rotate up and down on the multiple conveying racks 23 around the circumferential surfaces of the multiple second sprockets 24. The multiple groups of material transmission chains 3 drive the pallet goods to move longitudinally, which is convenient for horizontal feeding. At the same time, when the pallet goods enter between the L-shaped frame 4 and the hollow frame 5 from one side of the hollow frame 5, the fixed baffle 40 is used to block the pallet goods to prevent the pallet goods from falling longitudinally outside the L-shaped frame 4 and the hollow frame 5, thereby realizing longitudinal material connection of the pallet goods;

[0107] When the pallet is transported longitudinally, the output end of the drive motor 51 is started to rotate, and the rotation of the output end of the drive motor 51 drives one of the second synchronous wheels 52 to rotate, and the transmission cooperation of the second synchronous wheel 52 and the second synchronous belt 53 drives the bidirectional screw 46 on one side to rotate, and then the transmission cooperation of the first synchronous wheel 47 and the first synchronous belt 48 makes the two bidirectional screws 46 rotate simultaneously. When the bidirectional screw 46 rotates forward, the threaded barrels 55 on the front and rear sides move inward on the surface of the bidirectional screw 46 at the same time, and the movement of the threaded barrel 55 drives the two cross plates 57 to move inward at the same time. The movement of the cross plate 57 drives the mounting frame 59 and multiple guide wheels 60 to move inward. When the cross plate 57 moves inward until it contacts 1, the drive motor 51 can be turned off, and the extension end of the cylinder 61 is started to extend. The extension of the extension end of the cylinder 61 pushes the mounting frame 59 and multiple guide wheels 60 to move upward, and the movement of multiple guide wheels 60 makes it easy to correspond to the position of the pallet, so as to play a protective effect during the longitudinal transportation of the pallet to prevent the pallet from falling.
