Description

Technical Field

[0001] This invention belongs to the field of logistics technology, specifically relating to a multi-layer dual-machine RGV conveyor system and its usage method. Background Technology

[0002] Existing RGVs mainly consist of a vehicle frame, drive and walking mechanism, conveying mechanism (commonly chain conveyors, roller conveyors, etc.), and power system, enabling efficient, precise, and automated material flow along a fixed path. They are widely used in the production and logistics processes of various industries such as tobacco, home appliances, pharmaceuticals, food, automobiles, and military. Additionally, there is currently a "Multi-layer Rail-type Intelligent Transport Vehicle (RGV)," patent number CN211310708U, which adds a lifting conveyor platform to the existing RGV structure, realizing material delivery to multi-layer conveyor lines within a single-layer space.

[0003] The current mainstream RGV operation process mainly includes four stages: receiving instructions, executing movement, precise docking, and material transfer. While the execution movement stage is characterized by high speed and precision, it is generally equipped with only a single-layer platform, resulting in the transfer of only a limited amount of material per operation. The proposed "Multi-layer Rail-type Intelligent Conveyor Vehicle" suggests a platform with lifting capabilities, allowing docking with multiple conveyor lines during material transport; however, this still cannot solve the efficiency bottleneck due to the limited material carrying capacity per operation. Summary of the Invention

[0004] (a) Technical problems to be solved The technical problem to be solved by the present invention is how to provide a multi-layer dual-machine RGV conveying system and its usage method to solve the efficiency bottleneck of material carrying capacity limitation in a single operation and the single operation mode problem of conventional RGVs.

[0005] (II) Technical Solution To solve the above-mentioned technical problems, the present invention proposes a multi-layer dual-machine RGV conveying system, which includes: dual-machine RGV (1) and conveying line (2). The dual-machine RGV (1) includes: a buffer rack (11), a lifting and transfer device (12), a dual-machine body (13), a bottom vehicle body (14), a mechanical buffer mechanism (15), a guide rail (16), and a material box (17). The buffer rack (11) consists of several pairs of longitudinally arranged ratchet claws (110) for multi-layer buffering of the material bin (17); The lifting and transfer device (12) is located below the buffer rack (11) and is used to move the material box (17) up and down; The two locomotive bodies (13) are placed side by side on the bottom car body (14), and each car body contains a set of buffer racks (11) and a lifting and transfer device (12). The bottom vehicle body (14) is used to support the dual-machine body (13) to move at high speed on the guide rail (16), and the mechanical buffer mechanism (15) provides mechanical limit protection for the vehicle body during operation. The hopper (17) is a conventional industrial hopper with slots at both ends for support; The conveyor line (2) is a chain or roller conveyor line, arranged side by side.

[0006] The present invention also provides a method of using a multi-layer dual-machine RGV conveying system. When there is a large demand for conveying at the output position of the material box (17) and there is a delay in receiving at the receiving station, the buffer capacity of the conveying line (2) is limited and it is easy to cause interference to the conveying of the cross line. At this time, the dual-machine RGV (1) buffers the redundant material box (17), and when the receiving station has the conditions, the material box (17) is transferred and output.

[0007] The present invention also provides a method of using a multi-layer dual-machine RGV conveying system. When there is a demand for long-distance large-volume conveying, the dual-machine RGV (1) goes to the output line and cooperates with the dual conveyor lines to collect and buffer the material box (17) in a dual channel. After the goods are picked up, they are quickly moved to the receiving line via the guide rail (16), and the dual machines simultaneously transfer the material box (17).

[0008] The present invention also provides a method of using a multi-layer dual-machine RGV conveying system. When there is a need for material exchange and conveying, the dual-machine RGV (1) and the dual conveyor lines (2) respectively carry out the swallowing and spitting operations of the material box.

[0009] (III) Beneficial Effects This invention proposes a multi-layer dual-machine RGV conveyor system and its usage method, which improves operational efficiency in three aspects: (1) By increasing the utilization rate of the vertical space of the RGV body, the material conveying capacity of the RGV in a single operation is greatly improved, and a buffer function is provided; (2) By using a dual-body arrangement, the amount of material transported on track can be increased; (3) By using dual-machine throughput allocation, the difficulty of logic control can be effectively reduced. The cargo carried by the machine can be throughputed and discharged at the same time, which is suitable for material-intensive demand scenarios. Attached Figure Description

Detailed Implementation

[0011] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0012] To address the efficiency bottleneck caused by the limited material carrying capacity of current RGVs in a single operation, a multi-layer dual-machine RGV conveying system is proposed. This system can improve operational efficiency in three aspects: (1) By increasing the utilization rate of the vertical space of the RGV body, the material conveying capacity of the RGV in a single operation is greatly improved, and a buffer function is provided; (2) By using a dual-body arrangement, the amount of material transported on track can be increased; (3) By using dual-machine throughput allocation, the difficulty of logic control can be effectively reduced. The cargo carried by the machine can be throughputed and discharged at the same time, which is suitable for material-intensive demand scenarios.

[0013] The multi-layer dual-machine RGV conveying system includes: dual-machine RGV (1) and conveying line (2).

[0014] The dual-machine RGV (1) includes: a buffer rack (11), a lifting and transfer device (12), a dual-machine body (13), a bottom vehicle body (14), a mechanical buffer mechanism (15), a guide rail (16), and a material box (17), etc.

[0015] The buffer rack (11) consists of several pairs of longitudinally arranged ratchet claws (110) for multi-layer buffering of the material bin (17).

[0016] The ratchet pawl (110) includes a pawl (1101), a rotating shaft (1102), and a limiting pin (1103). The pawl (1101) can rotate around the rotating shaft (1102), and the limiting pin (1103) limits the rotation angle of the pawl (1101).

[0017] The lifting and transferring device (12) is located below the buffer rack (11) and is used to move the material box (17) up and down. The lifting and transferring device (12) includes: a conveying tray (120), a lifting rod (121), and a cylinder (122). The conveying tray (120) is above the lifting rod (121), and the lifting rod (121) moves up and down under the drive of the cylinder (122). Roller or chain conveyors are arranged on the conveying tray (120) and are treated with anti-slip measures.

[0018] The two locomotive bodies (13) are placed side by side on the bottom car body (14), and each car body contains a set of buffer racks (11) and a lifting and transfer device (12).

[0019] The mechanical buffer mechanism (15) and guide rail (16) are similar in function to the conventional RGV structure, and will not be described in detail here.

[0020] The bottom vehicle body (14) can carry the dual-machine body (13) to move at high speed on the guide rail (16), and the mechanical buffer mechanism (15) provides mechanical limit protection for the vehicle body during operation.

[0021] The hopper (17) is a conventional industrial hopper with slots at both ends for support.

[0022] The material box (17) is placed on the conveyor tray (120). It can be lifted by the lifting rod (121) under the action of the cylinder (122). When the material box (17) contacts the chuck (1101), the chuck (1101) will rotate clockwise around the rotating shaft (1102) under the push of the material box (17), without interfering with the rise of the material box (17). When the height of the material box (17) reaches above the ratchet chuck (110), the chuck (1101) rotates around the rotating shaft (1102) to reset (horizontal state). At the same time, the lifting rod (121) can be lowered under the action of the cylinder (122). At this time, the chuck (1101) carries the material box. The corresponding ratchet chuck (110) can be selected according to the number of material boxes (17) that need to be buffered, and the lifting and buffering are completed one by one.

[0023] When the material box (17) needs to be released from the buffer rack (11), the conveyor tray (120) can first lift the material box (17) a certain distance under the lifting action of the lifting rod (121). At this time, the motor drives the rotating shaft (1102) to rotate clockwise, so that all the claws (1101) under the target material box can be released. At this time, the lifting rod (121) descends, so that the conveyor tray (120) can carry the material box (17) to be lowered.

[0024] The conveyor line (2) can be a chain or roller conveyor line, arranged side by side.

[0025] The conveying pallet (120) can transfer the load box (17) on it between the twin RGV (1) and the conveyor line (2) under the action of roller or chain conveyor.

[0026] This invention has multiple application scenarios and can solve the conveying needs in various conveying production applications.

[0027] (1) When there is a large demand for conveying at the output position of the material box (17) and there is a delay in receiving at the receiving station, the buffer capacity of the conveyor line (2) is limited and it is easy to cause interference to the conveying of the cross line. At this time, the redundant material box (17) can be buffered by the dual-machine RGV. When the receiving station has the conditions, the material box (17) can be transferred and output.

[0028] (2) When there is a need for long-distance and large-volume transportation, the dual RGV (1) can be used to collect and buffer the material box in two channels at the output line. After the goods are picked up, they are quickly moved to the receiving line via the guide rail. The two machines simultaneously transfer the material box, which greatly improves the single transfer volume and transfer speed.

[0029] (3) When there is a need for material interaction and conveying, the dual RGV (1) can be used in conjunction with the dual conveyor lines (2) to perform swallowing and spitting operations on the material box respectively, thereby improving the interaction efficiency.

[0030] Example 1: The dual-unit RGV described is for illustrative purposes only, and can be expanded to three or more units as needed.

[0031] The dual-machine RGV conveying system consists of dual-machine RGV (1) and conveying line (2).

[0032] The dual-machine RGV (1) consists of a buffer rack (11), a lifting and transfer device (12), a dual-machine body (13), a bottom vehicle body (14), a mechanical buffer mechanism (15), a guide rail (16), and a material box (17).

[0033] The buffer rack (11) consists of several pairs of longitudinally arranged ratchet pawls (110).

[0034] The ratchet pawl (110) consists of a pawl (1101), a rotating shaft (1102), and a limiting pin (1103). The pawl (1101) can rotate around the rotating shaft (1102), and the limiting pin (1103) limits the rotation angle of the pawl (1101).

[0035] The lifting and transfer device (12) consists of a conveying tray (120), a lifting rod (121), and a cylinder (122).

[0036] The conveying pallet (120) is equipped with rollers or chain conveyors and is treated with anti-slip measures.

[0037] The two locomotive bodies (13) are placed side by side on the bottom car body (14), and each car body contains a set of buffer racks (11) and a lifting and transfer device (12).

[0038] The mechanical buffer mechanism (15) and guide rail (16) are similar in function to the conventional RGV structure, and will not be described in detail here.

[0039] The bottom vehicle body (14) can carry the dual-machine body (13) to move at high speed on the guide rail (16), and the mechanical buffer mechanism (15) provides mechanical limit protection for the vehicle body during operation.

[0040] The hopper (17) is a conventional industrial hopper with slots at both ends for support.

[0041] The material box (17) is placed on the conveyor tray (120). It can be lifted by the lifting rod (121) under the action of the cylinder (122). When the material box (17) contacts the chuck (1101), the chuck (1101) will rotate clockwise around the rotating shaft (1102) under the push of the material box (17), without interfering with the rise of the material box (17). When the height of the material box (17) reaches above the ratchet chuck (110), the chuck (1101) rotates around the rotating shaft (1102) to reset (horizontal state). At the same time, the lifting rod (121) can be lowered under the action of the cylinder (122). At this time, the chuck (1101) carries the material box. The corresponding ratchet chuck (110) can be selected according to the number of material boxes (17) that need to be buffered, and the lifting and buffering are completed one by one.

[0042] When the material box (17) needs to be released from the buffer rack (11), the conveyor tray (120) can first lift the material box (17) a certain distance under the lifting action of the lifting rod (121). At this time, the motor drives the rotating shaft (1102) to rotate clockwise, so that all the claws (1101) under the target material box can be released. At this time, the lifting rod (121) descends, so that the conveyor tray (120) can carry the material box (17) to be lowered. The conveyor line (2) can be a chain or roller conveyor line, arranged side by side.

[0043] The conveying pallet (120) can transfer material boxes (17) on it between the conveyor line (2) under the action of rollers or chain conveyors.

[0044] This invention addresses the efficiency bottleneck caused by the limited material carrying capacity of current RGVs in a single operation by proposing a multi-layer, dual-machine RGV conveying system. This system improves operational efficiency in three ways: (1) By increasing the utilization rate of the vertical space of the RGV body, the material conveying capacity of the RGV in a single operation is greatly improved, and a buffer function is provided; (2) By using a dual-body arrangement, the amount of material transported on track can be increased; (3) By using dual-machine throughput allocation, the difficulty of logic control can be effectively reduced. The cargo carried by the machine can be throughputed and discharged at the same time, which is suitable for material-intensive demand scenarios.

[0045] This invention includes, but is not limited to, the following three application scenarios: (1) When there is a large demand for conveying at the output position of the material box and there is a delay in receiving at the receiving position, the buffer capacity of the conveyor line is limited and it is easy to cause interference to the conveying of the cross line. At this time, the redundant material box can be buffered by the dual RGV. When the receiving position has the conditions, the material box can be transferred and output.

[0046] (2) When there is a need for long-distance and large-volume transportation, the dual RGV machines can be used in conjunction with the dual conveyor lines to collect and buffer the material boxes in a dual-channel manner at the output line. After the goods are picked up, they are quickly moved to the receiving line via the guide rail. The two machines simultaneously transfer the material boxes, which greatly improves the single transfer volume and transfer speed.

[0047] (3) When there is a need for material exchange and transportation, the dual RGV can be used in conjunction with the dual conveyor lines to perform swallowing and spitting operations on the material box, thereby improving the efficiency of the exchange.

[0048] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
