Description

Technical Field

[0001] The invention relates to the field of sorting equipment, and in particular to a multi-track sorting trolley conveying mechanism. Background Art

[0002] With the development of China's logistics industry, there are higher requirements for the efficiency of sorting systems, which require faster speed, higher efficiency, stable and reliable operation, and lower energy consumption. Some manufacturers also use double-layer sorting devices. Common sorting trolley structures, such as the cross-belt sorting trolley disclosed in patent announcement number: CN 109956282 A, are driven by primary and secondary, and the first stages are connected to each other, running on the rack to transport goods, usually single-layer, but with low efficiency.

[0003] Later, a double-layer structure appeared. The existing double-layer sorting carts, such as the patent announcement number: CN 109466904A discloses a double-car double-layer cross-belt logistics automatic sorting system, or CN 105035673 A is a conjoined double-layer cross-belt sorting machine, which connects the carts to each other; the former is a two-layer structure, which is completely superimposed, using two sets of power sources, which consumes a lot of power, and the corresponding structure is also responsible. Since the power source is a secondary and primary structure, the weight of the whole device is greatly increased, and the bearing capacity of the ordinary frame can only support two layers, and it is difficult to perform stacking.

[0004] The latter is achieved by connecting the trolleys, and the connecting cantilever not only plays a connecting role, but also ensures that the trolleys can be linked when turning, so it must be installed on each trolley on the upper and lower layers. Generally, the cross-belt trolley is continuously arranged with 24 trolleys, and there must be 24 cantilevers, so the load-bearing capacity requirements of the frame are greatly increased, and it is even more difficult to bear for the stacking of more than 3 layers. Summary of the invention

[0005] In order to solve the above technical problems, the present invention proposes a multi-track sorting trolley conveying mechanism, comprising at least two layers of support frames, the support frames are provided with multiple layers of slide rails, the slide rails are provided with a plurality of trolleys, the trolleys are arranged continuously head to tail, and the trolleys at different layers are provided with connecting rods, and the connecting rods are used to connect one group of corresponding trolleys at the upper and lower layers.

[0006] The bottom layer of the support frame is provided with a power mechanism for driving the trolley to move.

[0007] Preferably, material unloading openings are provided on both sides of the trolley.

[0015] The multi-track sorting trolley conveying mechanism proposed in the present invention has the following beneficial effects: the mechanism uses a multi-layer conveying mechanism, and the weight of the trolley is pressed on the frame of each layer, thereby reducing the support force requirement for the frame.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1 , Figure 3 As shown, the present invention proposes a multi-track sorting trolley conveying mechanism, comprising at least two layers of support frames 1, wherein the support frame 1 is provided with multiple layers of slide rails 2, and the slide rails 2 are provided with a plurality of trolleys 3, the trolleys 3 are arranged continuously head to tail, and the trolleys 3 of different layers are provided with connecting rods 4, and the connecting rods 4 are used to connect one group of corresponding trolleys 3 of the upper and lower layers, and the bottom layer of the support frame 1 is provided with a power mechanism 5 for driving the trolley 3 to move, wherein the structure of the trolley 3 is a relatively mature trolley 3 design, and a U-shaped support rail is provided at the bottom of the support frame 1 for supporting the trolley 3, and the U-shaped support rail is fixed on the support frame 1, and its power mechanism 5 is also driven by primary and secondary. Specifically, the patent announcement numbers are: CN 207998259U, CN205045406U and CN 109956282 A, etc. The structures of the sorting trolley 3 are not repeated in this application, and it should be noted in the application that only the trolley 3 of the bottom layer has an electrode sheet 9 for driving, while the trolley 3 of the upper layer is not provided with an electrode sheet 9.

[0023] In this embodiment, a three-layer structure is selected, but it is not limited to three layers, and can be two layers, four layers, or five layers. Figure 1 As shown, the two ends of the trolley 3 are respectively connected with a second joint bearing 13 and a pin shaft 14, and the pin shaft 14 is inserted into the second joint bearing 13. The two ends of the trolley 3 are connected to each other through the second joint bearing 13. When in the turning section, the position can be adjusted to facilitate turning. At the same time, the trolley 3 of each layer is pressed on the support frame 1 separately, and the support frame 1 includes relatively arranged columns 7, and support feet 8 are arranged between the columns 7. The support feet 8 are provided with the slide rail 2, and the trolley 3 is mounted on the slide rail 2. The slide rail 2 is L-shaped, and the slide rail 2 is arranged on each layer of the support feet 8. The middle is empty, which is convenient for the trolley 3 to connect the connecting rod 4 when going up and down. The use of the L-shaped slide rail 2 can effectively ensure that the walking wheels and the limiting wheels of the trolley 3 can be pressed on the slide rail 2 during transportation to ensure stability.

[0024] The unloading grids 6 are arranged on both sides of the trolley 3, and the goods slide down from both sides of the trolley 3 and are sorted according to the types of goods.

[0025] Among them, it should be noted that: due to the large number of trolleys 3, generally 24 or more can be set, and since the length of each car has deviations, the deviation will increase when the number increases, so the upper and lower cars cannot be aligned, which has a certain impact during assembly or driving, and when starting and stopping, the upper car that is not connected to the power source has a buffer force, which affects the entire equipment structure, so a floating mechanism is provided between the connecting rod 4 and the trolley 3, and the floating mechanism is used to adjust the length deviation between the trolleys 3 on different layers. The floating mechanism includes connecting pieces 10 respectively fixed on the trolley 3 fuselage and the connecting rod 4, and gas springs 12 are connected between the connecting pieces 10. A first joint bearing 11 is provided between the gas spring 12 and the connecting piece 10. When the trolleys 3 of the upper adjacent layers are initially installed, when the upper and lower cars cannot be completely aligned, the connecting rod 4 is difficult to install. By providing the gas spring 12 and the joint bearing, the position of the upper and lower cars is slightly adjusted, the gas spring 12 shrinks or stretches, and cooperates with the first joint bearing 11 to rotate, so that the installation position is aligned;

[0026] In addition, when the trolley 3 is started or stopped, and the upper trolley 3 is no longer pulled by power, the gas spring 12 can buffer part of the force to prevent damage to the connecting rod 4 and increase the service life of the equipment.

[0027] Another embodiment of this solution is: the floating mechanism includes connecting plates respectively fixed to the trolley body and the connecting rod, a hydraulic cylinder is connected between the connecting plates, a spring is sleeved outside the hydraulic cylinder, the spring is connected to the output end of the hydraulic cylinder, and a first joint bearing is arranged between the hydraulic cylinder and the connecting plate. Through the cooperation of the hydraulic cylinder and the spring, a greater force can be endured.

[0028] Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
