Description

Technical Field

[0001] The present invention belongs to the field of logistics transportation equipment, and particularly relates to a shaft-type logistics transmission system and method. Background Art

[0002] In large office buildings and residences such as general hospitals, hotels, and guesthouses, a large amount of materials or garbage need to be cleared every day. If transported manually in the elevator, it not only wastes a large amount of human resources, but also occupies public resources such as elevators, and greatly affects work efficiency.

[0003] In the comparative document with the patent number CN202010638643.4, a box-type logistics shaft transmission mechanism is disclosed. Although it solves the problem of independent transportation of goods in large office buildings, firstly, the transportation scheme in this comparative document is carried out in the form of a hanging basket, and its transportation intensity and stability cannot be guaranteed; secondly, the device in the comparative document can only perform two-way transportation in a single channel. When the demand is large, the transportation pressure can only be relieved by increasing the number of hanging baskets, which is not only costly but also occupies a large space, and the transportation efficiency is low; thirdly, before transportation, the weight of the goods cannot be detected in time. When the goods are overloaded, it is impossible to make a pre-judgment in advance, and accidents such as overloading and falling are likely to occur during transportation; finally, the receiving and sending of goods can only be carried out separately by one hanging basket, and there is a common pickup port for receiving and sending, which affects the receiving and sending efficiency.

[0015] To achieve the above object, on the other hand, the present invention also provides a shaft-type logistics transmission method, which is implemented by the above shaft-type logistics transmission system, and includes the following steps:

[0016] Weighing and detection: Place the goods to be transported on the weighing roller path. If the goods exceed the weight limit, the station safety door is in the closed state, and at the same time the feeding roller path stops running; if the goods do not exceed the weight limit, the station safety door opens, and at the same time the feeding roller path starts to convey the goods to the first buffer roller path;

[0017] Pick-up transportation: the diverter drives the lifting vehicle to move to the first buffer roller, fixes the goods in the vehicle body through the conveyor belt assembly, and the lifting vehicle moves along the transportation shaft to the corresponding floor, and then transports the goods to the corresponding second buffer roller;

[0018] Shipping: the safety door of the station is opened, and the goods are transported from the second buffer roller conveyor to the corresponding receiving roller conveyor to wait for picking up;

[0019] One-way conduction: first define the first track and the second track as an ascending channel and a descending channel respectively. When the lifting vehicle ascends or descends in one direction along the transport shaft, the moving track in the track switch can move between the guide rails to conduct the lifting vehicle in one direction;

[0020] Reverse switching: When the wrong cargo is loaded, the lift truck needs to change tracks to turn. The movable track in the switch can move between the guide rails. The lift truck runs to the movable track, and the movable track moves horizontally to dock with another track, thereby switching the lift truck to move in the reverse direction.

[0021] Compared with the existing technology, the present invention has the following beneficial effects:

[0022] 1. The shaft-type logistics transmission system of the present invention is provided with a track assembly with multiple tracks in the transport shaft, and a movable lifting vehicle is installed on the track assembly to transport goods. The track conveying structure has higher strength and can withstand a larger load. The transfer vehicle can realize one-way transportation or transfer transportation in a single shaft through the diverter, and its work efficiency is higher and the space occupied is small. The self-weighing sending and receiving station can not only independently send and receive goods at the same time to improve the sending and receiving efficiency, but also can weigh the goods in advance, block overweight goods, and prevent overloading accidents.

[0023] 2. The sliding seat on the lifting vehicle of the present invention has its own power device, and moves through the cooperation between the driving gear and the gear sleeve on the guide rail, so it has higher positioning accuracy and strength.

[0024] 3. The first rail, the second rail and the movable rail of the present invention are provided with communication copper rails, which can charge the batteries on the lifting vehicle and communicate, have a longer practical life, and can also move with the movement of the movable rails. They will not be bent multiple times like communication wires, thereby improving their service life.

[0025] 4. The lift truck in the present invention is provided with a storage battery, and a communication wire is arranged on its back. It can not only be charged and communicate through the communication copper rail in the track, but also communicate through an external cable. When the communication guide rail is disconnected or fails, it can further play a role in ensuring communication safety.

[0026] 5. The track assembly in the present invention includes a detachable frame assembly, which can be custom-installed according to the floor height of different floors and is convenient for disassembly and replacement.

[0027] 6. C-shaped first clamping grooves are respectively arranged on both sides of the first track, the second track and the moving track in the present invention. On the sliding seat of the lift truck, a first pulley and a second pulley with perpendicular axes are respectively arranged. By clamping the two pulleys in the first clamping groove, the sliding seat can be limited in both the left-right direction and the front-back direction, and it can effectively prevent the sliding seat from tipping over or jamming due to the force on the vehicle body.

[0028] 7. The weighing and receiving and dispatching station in the present invention includes a feeding roller path and a receiving roller path arranged up and down. It can receive and dispatch materials simultaneously, and goods can be parked on the feeding roller path and the receiving roller path, thus playing a certain buffering role. A weighing roller path is arranged at the loading end of the feeding roller path, which can weigh the goods before the feeding roller path conveys them. If overloaded, the safety door of the station cannot be opened, so that overloaded goods can be automatically blocked to prevent the danger of overloaded falling.

[0029] 8. The top of the outer circumference of the supporting pulley in the conveyor belt assembly of the lift truck in the present invention is higher than the top of the outer circumference of the driving pulley, so that the height of the middle part of the conveyor belt can be higher than the height of its two ends, and there is a certain slope from the two ends of the conveyor belt to the middle. When the lift truck picks up and transports goods, the goods can be more easily and smoothly transported to the middle of the conveyor belt, and it is also smoother when unloading.

[0030] 9. A stopper is arranged at each of the cargo openings at both ends of the lift truck in the present invention, which can play a role in preventing the cargo from falling when the lift truck drives the cargo to move.

[0031] 10. The buffer roller path assembly in the present invention can play a role in buffering goods when the transported material flow is too large, preventing goods from being blocked at the first sending and receiving station, affecting the operation efficiency of the equipment, and a second stopper and a second retaining arm are also arranged in the buffer roller path assembly, so as to prevent the danger of goods falling from the buffer roller path.

[0032] 11. On both sides of the rail transfer device in the present invention, a car stopper is installed respectively. The car stopper is provided with a vertical elastic rod, and a plurality of stoppers are installed on the elastic rod. When the lifting vehicle is driven by the moving track to move horizontally, the car stopper can block the side of the vehicle body of the lifting vehicle as a whole, which not only has a good blocking effect, but also can prevent the vehicle body from tilting during the process of blocking the vehicle body, so as to damage the moving track and the sliding seat.

[0033] 12. The rail transfer device in the present invention can play three roles at the same time. First, it can play a role in connecting and conducting the tracks between two track components; second, it can play a role in changing the track and turning the moving vehicle; third, it can play a role in transferring the moving vehicle to the buffer roller table assembly.

[0034] 13. The shaft - type logistics transmission method in the present invention can, through the weighing detection step, predict in advance the overloading situation of goods and timely control the closing of the station safety door to block the goods. And due to the setting of the buffer roller table assembly, two through - ports can be set on the same floor, improving the material flow and transportation efficiency; and through the setting of the first track, the second track and the rail transfer device, one - way transportation and reverse track changing can be realized. When the goods are loaded wrongly, the moving vehicle can change the track and turn around to run, and it will not affect the normal operation of other moving vehicles.

[0064] Embodiment 2:

[0065] The shaft-type logistics transmission method in this embodiment is implemented through the shaft-type logistics transmission system in Embodiment 1. The method specifically includes the following steps:

[0066] Weighing detection: Place the goods to be transported on the weighing roller table 53. If the goods exceed the weight limit, the station safety door 7 is in the closed state, and at the same time, the feeding roller table 51 stops running; if the goods do not exceed the weight limit, the station safety door 7 opens, and at the same time, the feeding roller table 51 starts to convey the goods onto the first buffer roller table 61.

[0067] Goods pickup and transportation: The rail changer 3 drives the lift truck 4 to move to the first buffer roller table 61. The goods are fixed in the vehicle body 41 through the conveyor belt assembly 44. At this time, the first infrared sensor 453 senses the goods and lowers the first stop arm 452 in the first stopper 45 to block at the goods opening 43. The moving track 13 drives the lift truck 4 to move to the corresponding track and move it along the transportation shaft 1 to the corresponding floor, and then transports the goods to the corresponding second buffer roller table 62. The second servo motor 63 drives the second stop arm 64 to rotate towards the second buffer roller table 62 to block the goods.

[0068] Goods shipment: The corresponding station safety door 7 opens, and the goods are transported from the second buffer roller table 62 to the corresponding receiving roller table 52 for waiting to be picked up.

[0069] One-way transportation: First, define the first track 21 and the second track 22 as the ascending channel and the descending channel respectively. When the lift truck 4 moves unidirectionally up or down along the transportation shaft 1, the moving track 31 in the rail changer 3 can move between these two guide rails to connect them and transport the lift truck 4 unidirectionally.

[0070] Reverse track switching: When the goods are loaded incorrectly, the lift truck 4 needs to change the track for steering. The movable track 31 in the track switch 3 can move between the guide rails. The lift truck 4 runs to the movable track 31, and the movable track 31 translates and docks with another track, so as to switch the track of the lift truck 4 and make it move in the reverse direction.
