Description

Technical Field

[0001] The present invention relates to the technical field of sorting, and in particular to a motor-free express sorting trolley. Background Art

[0002] The logistics sorting system is a very advanced and efficient equipment that realizes the automation of logistics sorting. It not only improves the efficiency and speed of logistics sorting, but also improves the accuracy of sorting work. The express sorting trolley is a link in the express delivery of the logistics sorting system, which is used to complete the transmission of express from the charter plane to the sorting port.

[0003] The cross-belt sorting machine currently commonly used in logistics sorting equipment is a machine that evenly arranges carts (referred to as sorting carts) carrying small belt conveyors on a circular track. All sorting carts are connected to form a loop, and the main motor driving the sorting cart provides power to drive all carts to run in a circle on the track. Several sorting ports are arranged on both sides of the track. When the sorting cart moves to the destination sorting port, the sorting cart belt conveyor motor drives the belt to operate, causing the goods on the sorting cart belt to move horizontally, completing the task of sorting out the goods. Because the running direction of the belt conveyor on the sorting cart is cross-shaped with the circular running direction, it is called a cross-belt sorting machine.

[0004] In order to make the goods on the sorting trolley move laterally for unloading, a motor is arranged on the conventional sorting trolley, and the motor drives the belt conveyor to operate and drive the goods to move laterally for unloading.

[0005] A standard cross-belt sorter has a circular running speed of 2 m / s, a total track length of 120 m, a sorting trolley pitch of 0.6 m, a total number of 200 trolleys, and a belt conveyor motor power of 0.4 kW on each sorting trolley, which operates intermittently; the sorting trolley driving main motor power is 30 kW, which operates continuously. During the 60-second period of a sorting trolley running on the circular track, the motor of the sorting trolley only runs for 0.3 seconds when the sorting trolley passes the destination sorting port, so the vacancy rate of the sorting trolley belt conveyor motor is very high, resulting in large vacancy losses and waste of resources.

[0006] The belt conveyor on the sorting trolley needs to be specially equipped with power receiving components, and the circular track also needs to be equipped with a special sliding contact conductive system for the belt conveyor motor. In order to ensure the accurate operation of the sorting trolley motor, it must also be equipped with a corresponding belt conveyor motor control system, position monitoring module, communication module and sliding bus bar, etc. The equipment structure is complex, the number of lateral drive motors of the trolley increases, the cost increases, and the number of failure points also increases, reducing reliability.

[0007] In the prior art, the goods on the sorting trolley of the cross-belt sorting machine of the British Innotech Company are moved horizontally by friction wheels. The power for the horizontal movement of the goods is generated by an external cylinder that presses against the friction wheel on the trolley through a friction plate, forcing the friction wheel to rotate. Although there is no independent motor installed on the mobile sorting trolley, a set of pneumatic devices must be installed as a power source. However, the pneumatic device has a complex structure, high cost and unstable performance. Summary of the invention

[0008] In order to overcome the deficiencies of existing research, the present invention provides a motor-free express sorting trolley with a simple structure. It cleverly uses the power of the trolley to unload goods while adopting a mechanical synchronous drive method. It has a quick response, good synchronization, higher precision, and more stable reliability. There is no need for power receiving components on the transport trolley, which reduces the sliding contact conductive system.

[0055] The active chain transmission mechanism and the driven chain transmission mechanism are arranged vertically, so that the active chain lever 2.2 and the driven chain lever 3.2 intersect vertically in space to generate a driving connection.

[0056] The elastic member 5.3 is a spring, and the hook claw 5.2 is a U-shaped plate arranged roughly in a horizontal direction. The upper and lower rear sides of the U-shaped plate are respectively provided with left-bent supporting hook claws. A hanging rod 1 is vertically arranged in the middle of the U-shaped plate, and the hanging rod 1 is engaged with one end of the spring. A hanging rod 2 is fixed at a corresponding position on the fixed plate 5.1, and the other end of the spring is engaged with the hanging rod 2.

[0063] The cross section of the annular track 1.4 is circular.

[0064] The working principle and process of the present invention.

[0065] like Figure 1-6 As shown, the working process of this motorless express sorting cart.

[0066] Driven by the main drive, the transport trolley 1 moves forward, that is, the goods placed on the transport plate 6 move forward. When the transport trolley 1 approaches the destination, the goods need to move horizontally. The sensor on the hook device 5 senses the signal, and the electromagnet of the destination is energized to work. The electromagnet drives the push rod to push the rubber head 5.4 toward the transport trolley 1 to hit the hook, so that the hook 5.2 extends, so that the hook 5.2 is pre-blocked on the movement trajectory of the active chain lever 2.2.

[0067] The transport trolley 1 continues to move forward, and the extended hook 5.2 just hooks one of the active chain levers 2.2. The upper and lower two supporting hooks of the hook 5.2 hook the upper and lower parts of the active chain lever 2.2 respectively. The hook 5.2 is fixed on the fixed plate 5.1, and the fixed plate 5.1 is fixed on the hook support rod 4. The active chain lever 2.2 is subjected to the hooking force of the hook 5.2, and the active chain lever 2.2 causes the active chain 2.1 to move, and the part of the active chain lever 2.2 fixed on the joint of the active chain 2.1 moves. The part of the driven chain lever 3.2 fixed at the joint on the driven chain 3.1 is vertically intersected in space, so that the movement of the active chain 2.1 drives the active chain lever 2.2 to move. When the active chain lever 2.2 moves, it collides and blocks with the driven chain lever 3.2 to drive the driven chain lever 3.2 to move. The movement of the driven chain lever 3.2 drives the movement of the driven chain 3.1. The movement of the driven chain 3.1 drives the transport plate 6 to move. Therefore, the goods placed on the transport plate 6 are driven, and the goods move horizontally to achieve the purpose of unloading.

[0068] The transport trolley 1 moves forward until the active chain lever 2.2 disengages from the hook 5.2, and the sensor on the hook device 5 senses the stop signal, the electromagnet loses power, the spring return force causes the push rod to retract to the right, and then the rubber head 5.4 retracts to the right, at which time the hook 5.2 rotates to the right and is reset by the spring buffer.

[0069] This motorless express sorting trolley, when the main motor drives the transport trolley 1 to run at a constant speed on the circular track 1.4, the hook claw 5.2 is used to hook the active lever 2.2, and the main motor power that drives the transport trolley 1 to move in a circular direction is used to make the active lever 2.2 move in the opposite direction to the forward direction of the transport trolley 1, thereby driving the active chain transmission mechanism 2 to operate, and the active chain transmission mechanism 2 drives the driven chain transmission mechanism 3 to operate through the active chain lever 2.2 and the driven chain lever 3.3, and the operation of the driven chain transmission mechanism 3 drives the transport plate 6 to move horizontally to unload the goods.

[0070] In this motor-free express sorting trolley, the power for the lateral movement of the goods in the left and right directions is provided by the motor that drives the transport trolley 1 in circular motion. There is no need for an additional motor to drive the lateral movement. The structure is simple, the performance is more stable, and the cost performance is higher.

[0071] In this motorless express sorting trolley, no power receiving components are required on the transport trolley 1, which reduces the sliding contact conductive system. There is no need for corresponding driving lateral motion motor synchronous control system, position monitoring module, communication module and sliding busbar, etc. The equipment structure is simple, the cost is reduced, and at the same time, the failure points are reduced and the reliability is increased.

[0072] This motor-free express sorting trolley saves the motor and motor control system for driving the lateral movement of the transport trolley 1. The device for controlling the micro-motion of the hook 5.2 is completed by two electromagnets. The power of a single electromagnet is 20 watts, and the combined power of the two electromagnets is only 40 watts. The motor power of the traditional express sorting trolley with a motor is 400 watts, which reduces the power configuration by 90%, saves energy and reduces consumption, while being low-cost, simpler to control, and more reliable.

[0073] This motorless express sorting trolley, the transport trolley 1 adopts a rolling connection with a flanged wheel 1.3 and a matching circular track 1.4. During transportation, it has better guidance and the transport trolley 1 will not tilt. Even when unloading on the transport plate 6, the transport trolley 1 is not easy to tilt and leave the circular track 1.4. The rolling connection has low friction, and transportation is more labor-saving and fast.

[0074] In this motorless express sorting trolley, the transport plate 6 is formed by a fixed combination of evenly spaced long strips 6.1. The transport plate 6 with this structure has a certain friction force, and the goods are not easy to slide off when the transport plate 6 moves forward.

[0075] This motor-free sorting trolley has a simple structure, cleverly uses the forward power of the transport trolley, and adopts mechanical synchronous drive to unload, with rapid response, good synchronization, higher precision, and more stable reliability; the transport trolley 1 does not require power receiving components, reduces the sliding contact conductive system, and does not require a corresponding motor synchronous control system for driving the lateral movement, a position monitoring module, a communication module, and a busbar, etc. The equipment structure is simplified, energy-saving and consumption-reducing, cost-effective, cost-effective, reduced costs, reduced failure points, and increased reliability.
