Description

Technical Field

[0001] The invention relates to a single-module sorting trolley with good sorting effect and energy saving, belonging to the technical field of logistics sorting equipment. Background Art

[0002] Since the belt of the existing logistics sorting stretch section trolley is driven by a motor, in order to facilitate the installation of the trolley, the existing stretch section trolley is composed of two trolleys to form a module, and the motor and other protruding parts of one of the trolleys are installed inside the other trolley, thereby saving space. However, when one of the two trolleys is broken, both need to be disassembled for maintenance.

[0003] In addition, in the prior art, when the trolley reaches the designated position, the electric roller on the trolley drives the belt to one side through forward or reverse rotation to realize the sorting of the parcels. Since the upper end surface of the belt is horizontal, the belt mainly relies on friction to realize the conveyance of the parcels. When the belt conveys some parcels with smooth appearance and light weight, it is easy to slip, such as soft parcels and document parcels packaged in plastic bags, and the problem of sorting failure is easy to occur.

[0004] Furthermore, horizontal transmission of heavier packages requires greater transmission power and consumes more electricity. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a single-module sorting trolley with good sorting effect and energy saving, so as to solve the problem that the upper end surface of the belt of the existing trolley is horizontal, and when the belt conveys some packages with smooth appearance and light weight, it is easy to cause sorting failure.

[0006] The technical solution adopted by the present invention is: a single-module sorting trolley with good sorting effect and energy saving, including a frame, an electric roller, a driven wheel, a belt and a lifting mechanism, the electric roller is installed on the frame, the number of the driven wheels is set to be more than four and they are all rotatably connected to the frame; all the driven wheels cooperate with the electric roller to tighten the belt; the upper end surface of the belt is horizontal; the number of the lifting mechanisms is set to two groups and they are symmetrically distributed on both sides of the electric roller; the lifting mechanism can lift one end of the upper end surface of the belt upward.

[0007] Preferably, the two driven wheels adjacent to the electric roller along the extension direction of the belt are located on the inner side of the belt and respectively located on the lower left and lower right of the electric roller, and the electric roller is located on the outer side of the belt.

[0008] Preferably, the two driven wheels adjacent to the electric roller can move horizontally under the action of a lifting mechanism, and the two driven wheels adjacent to the left and right ends of the upper end surface of the belt can move vertically under the action of a lifting mechanism.

[0009] Preferably, the lifting mechanism includes an electric push rod, a first connecting rod and a second connecting rod, the number of the electric push rods is set to 2 and all are installed on the frame, the mounting shaft of the driven wheel adjacent to the electric roller is hinged to the telescopic end of one of the electric push rods, the upper ends of the first connecting rod and the second connecting rod are hinged to the mounting shaft of the driven wheel adjacent to one end of the upper end surface of the belt, the lower end of the first connecting rod is fixed to the mounting shaft of the driven wheel adjacent to the electric roller, and the lower end of the second connecting rod is hinged to the telescopic end of another electric push rod.

[0010] Preferably, the first connecting rod and the second connecting rod are of the same length.

[0011] Preferably, the driven wheel adjacent to the electric roller is slidably connected to the frame and can only slide in the horizontal direction.

[0012] Preferably, the driven wheel adjacent to the upper end surface of the belt is slidably connected to the frame and can only slide in the vertical direction.

[0013] Preferably, it also includes a shell, the frame, the electric roller, the driven wheel, the belt and the lifting mechanism are all installed inside the shell, the upper end of the shell is open and the horizontal end of the belt is slightly higher than the upper end of the shell.

[0014] Beneficial effects of the present invention:

[0015] 1. Compared with the prior art, the present invention optimizes the two-carriage-one-module system on the market into one-carriage-one-module system. When a car breaks down, one car can be directly dismantled for repair, thus saving labor.

[0016] 2. Compared with the prior art, the present invention optimizes the traditional motor-driven trolley structure into an electric roller drive, which has a simpler structure and can adjust the tension of the belt and the contact area between the electric roller and the belt through an adjustment mechanism, thereby adjusting the driving force of the electric roller.

[0017] 3. In particular, compared with the prior art, the present invention drives the driven wheel adjacent to the electric roller to move outward through the electric push rod, thereby driving the driven wheel adjacent to one end of the upper end surface of the belt to move upward, so that the upper end surface of the belt is tilted to one side, thereby facilitating the sorting of packages. For some packages with smooth appearance and light weight, the smooth appearance of the package itself is utilized to make the package slide to one side under the action of a smaller transmission force. For some heavier packages, the greater gravity of the package itself is utilized to make the package slide or roll to one side under the action of a smaller transmission force, thereby achieving smooth sorting of the packages and greatly saving electric energy; at the same time, it avoids the electric roller being in a high-load state all the time, thereby extending the service life of the electric roller.

[0018] 4. In particular, in the prior art, the belt expands and contracts due to heat, so the belt in the prior art is not an integral ring, but requires a connecting piece to connect the two ends of the curved belt, it is very inconvenient to adjust the tension of the belt, the belt connection is easy to break and maintenance is inconvenient; while the belt in the present invention is a complete ring, and the position of the driven wheel can be synchronously adjusted by using the left and right lifting mechanisms, so as to ensure that the belt is always tensioned, and it is very convenient to adjust the tension of the belt and avoid the problems of belt breakage and inconvenient maintenance.

[0019] 5. In particular, compared with the prior art, during the transportation of the parcel, the belt is slightly loosened by the lifting mechanism, so that the parcel is securely placed on the belt; when the trolley reaches the designated position, the belt is tightened while one side of the lifting mechanism is lifted, which facilitates the sorting of the parcel. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a schematic diagram of the overall structure of the present invention. DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Embodiment 1:

[0023] A single-module sorting trolley with good sorting effect and energy saving comprises a frame, an electric roller 1, a first driven wheel 2, a second driven wheel 4, a belt 3 and a lifting mechanism. Figure 1 As shown, the mounting shaft of the electric roller 1 is fixed on the frame, a first driven wheel 2 is respectively provided at the upper left and upper right of the electric roller 1, a second driven wheel 4 is respectively provided at the lower left and lower right of the electric roller 1, the electric roller 1, the first driven wheel 2, and the second driven wheel 4 tighten the belt 3, wherein the electric roller 1 is located on the outside of the belt 3, the first driven wheel 2 and the second driven wheel 4 are located on the inside of the belt 3, and the upper end surface of the belt 3 is horizontal.

[0024] In this embodiment, the first driven wheel 2 is slidably connected to the frame and can only slide in the horizontal direction, and the second driven wheel 4 is slidably connected to the frame and can only slide in the horizontal direction. The number of lifting mechanisms is set to two groups and is symmetrically distributed on the left and right sides of the electric roller 1.

[0025] Take the lifting mechanism on the right as an example. Figure 1As shown, the lifting mechanism includes an electric push rod 5, a first connecting rod 6 and a second connecting rod 7. The number of electric push rods 5 is set to 2 and they are symmetrically installed on the frame. The mounting shaft of the second driven wheel 4 on the right is hinged to the telescopic end 51 of the electric push rod on the left. The mounting shaft of the second driven wheel 4 on the right can slide back and forth under the drive of the electric push rod 5 on the left. The electric push rod 5 on the left stops working, and the position of the mounting shaft of the second driven wheel 4 on the right is fixed; the first connecting rod 6 and the second connecting rod 7 are of the same length, and the upper ends of the first connecting rod 6 and the second connecting rod 7 are hinged on the right. The first connecting rod 6 is hinged on the mounting shaft of the first driven wheel 2 on the right side, the lower end of the first connecting rod 6 is hinged on the mounting shaft of the second driven wheel 4 on the right side, and the lower end of the second connecting rod 7 is hinged on the telescopic end 51 of the electric push rod on the right side. When the telescopic ends 51 of the two electric push rods are extended synchronously, the second driven wheel 4 on the right side and the lower ends of the second connecting rod 7 move toward the middle at the same time, and the two electric push rods 5 drive the mounting shaft of the first driven wheel 2 on the right side to slide vertically upward through the first connecting rod 6 and the second connecting rod 7, thereby lifting the right end of the upper end surface of the belt 3, so that the parcels on the belt 3 can be sorted to the left. After the parcels are sorted, the second driven wheel 4, the first connecting rod 6 and the second connecting rod 7 on the right side are reset under the contraction of the two electric push rods 5, and the first driven wheel 2 on the right side is reset, and the upper end surface of the belt 3 is restored to the horizontal.

[0026] Similarly, the lifting mechanism on the left can be used to sort the parcels to the right. Since the belt 3 is inclined, a smaller transmission force can be used to smoothly sort the parcels. When the second driven wheel 4 expands outward, the contact area between the belt 3 and the electric drum 1 decreases, which just matches the smaller transmission force.

[0027] Since the second driven wheel 4 expands outward and the first driven wheel 2 moves upward, the belt 3 will be tightened. Therefore, when the belt 3 is horizontal, it is necessary to adjust the belt 3 to be in a slightly loose state. When the belt 3 is in a horizontal position, the package is securely placed on the belt 3 by slightly loosening the belt 3. When the trolley reaches the designated position, the belt 3 is tightened while being lifted by one side of the lifting mechanism to facilitate the sorting of packages.

[0028] In addition, due to thermal expansion and contraction, the belt 3 in the prior art is not an integral ring, but requires a connector to connect the two ends of the curved belt 3. It is very inconvenient to adjust the tension of the belt 3, and the connection of the belt 3 is easy to break and inconvenient to maintain; while the belt 3 in the present invention is a complete ring, and the positions of the first driven wheel 2 and the second driven wheel can be adjusted synchronously by the left and right lifting mechanisms, so as to ensure that the belt 3 is always tensioned, and the tension of the belt 3 is very convenient to adjust and the problem of belt 3 breakage and inconvenient maintenance is avoided. The belts 3 on all the trolleys are lifted or lowered synchronously to ensure that the heights of all the trolleys are consistent.

[0029] The present embodiment also includes a rectangular hollow shell, the frame, the electric roller 1, the first driven wheel 2, the second driven wheel 4, the belt 3 and the lifting mechanism are all installed inside the shell, the upper end of the shell is open and the horizontal end of the belt 3 is slightly higher than the upper end of the shell. The shell is provided for aesthetics and to prevent bag jams.

[0030] The switch of the electric push rod 5 is installed on the outer side wall of the shell for easy operation.

[0031] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
