Description

Technical Field

[0001] This utility model belongs to the field of sorting cart technology, and relates to a narrow-band sorting cart. Background Technology

[0002] During the sorting process of the logistics sorting machine, the narrow-belt sorting trolley (approximately 100mm wide) moves forward. Guided by a cross-shaped guide rail, the bottom drive slider moves the circular belt in a circumferential direction, thus achieving sorting by the trolley. The sorting trolley... Figure 1 As shown, the sorting slider 102 on the sorting trolley is fixedly connected to the horizontal section below the sorting belt 101. The sorting slider 102 is slidably connected to the sorting chute 104 provided at the lower part of the trolley frame 103. The drive wheel 105 installed below the sorting slider 102 is driven by the forward movement of the sorting trolley and the cross-shaped guide rail 18, as shown. Figure 2 As shown, the sorting trolley moves forward, and the sorting belt moves left or right to perform sorting. When the trolley reaches the end of the sorting machine, it moves to the horizontal section below the sorting machine, and finally reaches the starting end of the sorting machine, with the cooperation of the sorting machine's circumferential chain, guide rails, and wheels. Figure 3 As shown, the sorting method of the sorting machine uses a cross-shaped guide rail 18. Before the sorting trolley 19 needs to sort to one side, the position of the sorting trolley is not fixed when it travels from the bottom section to the top section of the sorting machine. It is necessary to use a pre-sorting slider and a positioning reading device to pre-sort it to one side (from left to right or from right to left), which results in a longer pre-sorting stroke and more complex control. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a narrow-strip sorting trolley that is easier to control and has a shorter pre-sorting stroke.

[0004] The technical solution adopted by this utility model is as follows: a narrow belt sorting trolley, characterized in that it includes a sorting belt, a trolley frame, a slider, and a sorting drive wheel. Two pairs of support rollers are symmetrically arranged at both ends of the trolley frame. The slider is slidably connected to a guide rail provided at the lower part of the trolley frame. A roller frame is fixedly connected below the slider. Two drive rollers are rotatably connected to the left and right sides of the roller frame. A sorting drive wheel is rotatably connected below the roller frame. The two free ends of the sorting belt pass over the two pairs of support rollers and the two drive rollers respectively and are connected to the fixed parts at the bottom of both ends of the trolley frame. The fixed parts include a frame plate, a pressure plate, and bolts. The frame plate is horizontally set on the trolley frame. The pressure plate presses the ends of the sorting belt onto the frame plate and locks them with multiple bolts. The roller frame is a square frame structure with drive rollers rotatably connected at both ends. The width of the sorting belt is less than 200mm.

[0005] Furthermore, both ends of the aforementioned trolley frame are equipped with traveling wheels and directional wheels.

[0006] Furthermore, a sprocket is provided at the bottom of the aforementioned trolley frame to drive the trolley frame forward.

[0007] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model adopts an innovative belt winding method. Two pairs of support rollers are wound around to two symmetrical drive rollers installed on the bottom slider of the sorting trolley. The drive rollers act as movable pulleys. The drive rollers travel a certain distance on one side, and the top belt travels twice the distance in the opposite direction. Through the centering mechanical structure on the sorting machine, the sorting trolley can be automatically positioned at the left or right center of the sorting trolley's travel direction at the beginning. In conjunction with the belt traveling mechanism of this utility model, if sorting is required in either direction, the trolley can be controlled to move towards that side. The top section can be sorted by traveling halfway. The structure is simplified, the control is simpler, the pre-sorting stroke is shorter, the overall sorting machine setup is shorter, and the cost is lower. Attached Figure Description

[0017] The present invention will be further described below with reference to specific embodiments.

[0018] Example 1: As Figure 4-9As shown, a narrow-belt sorting trolley includes a sorting belt 1, a trolley frame 2, a slider 3, and sorting drive wheels 4. Two pairs of support rollers 6 are symmetrically arranged at both ends of the trolley frame 2. The slider 3 is slidably connected to a guide rail 5 at the bottom of the trolley frame 2. A roller frame 9 is fixedly connected below the slider 3. Two drive rollers are rotatably connected to the left and right sides of the roller frame 9. The sorting drive wheels 4 are rotatably connected below the roller frame 9. The two free ends of the sorting belt 1 pass over the two pairs of support rollers 6 and the two drive rollers 8 respectively and are connected to the fixing parts 7 at the bottom of both ends of the trolley frame 2. The fixing parts 7 include a frame plate 14, a pressure plate 15, and bolts 16. The frame plate 14 is horizontally arranged on the trolley frame 2. The pressure plate 15 presses the ends of the sorting belt 1 onto the frame plate 14 and locks them with multiple bolts 16. The roller frame 9 has a square frame structure, with drive rollers 8 rotatably connected to the openings at both ends. The width of the sorting belt 1 is less than 200mm.

[0019] The aforementioned trolley frame 2 is equipped with walking wheels 10 and directional wheels 11 at both ends. The walking wheels 10 travel on the sorting machine's track, while the directional wheels 11 are oriented and abut against the side wall of the side guide rail, achieving directional travel and lateral load-bearing.

[0020] The bottom of the aforementioned trolley frame 2 is equipped with a sprocket 17 that drives the trolley frame 2 to move forward. Driven by the chain of the sorting machine, the sprocket causes the trolley frame 2 to move forward.

[0021] Working principle: such as Figure 9 As shown, when the sorting trolley moves from the end of the sorting machine to the initial horizontal position, the drive wheel of the sorting trolley is automatically positioned in the directional guide groove 12 in the middle of the sorting machine. When sorting needs to be done to one side, the drive wheel is controlled to move to the other side of the sorting by the sorting slider 13, thereby realizing the sorting action of the sorting trolley.

[0022] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
