Description

Technical Field

[0001] The utility model relates to the field of logistics sorting, in particular to a turning track, a track component and a sorting device. Background Art

[0002] The track assembly is a fundamental component of the cross-belt sorter. It typically includes at least two curved tracks. When a sorting cart reaches a curved track, centrifugal force can cause packages on the cart to shift position or even fall off the cart, severely impacting sorting accuracy and safety.

[0003] Therefore, in order to overcome the centrifugal force of the sorting trolley at the turning track, the prior art proposes a structure in which the inner and outer tracks of the turning track are low on the inner side and high on the outer side. For example, the authorization announcement number CN 209701605 U is such a structure.

[0004] In this structure, the top surface of the frame web and the inner surface of the frame wing are at an angle. This structure causes the horizontal limit wheels on both sides of the sorting trolley to not maintain a fully fitted state with the frame wing when the running wheels of the sorting trolley move on the top surface of the frame web. This makes it easy for the horizontal limit wheels to be locally worn or over-pressure damaged when moving on the turning track, increasing the failure rate. Utility Model Content

[0005] The purpose of the present invention is to solve the above problems in the prior art and to provide a turning track, a track assembly and a sorting device.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] The turning track includes an inner curve and an outer curve arranged concentrically, the inner curve includes an inner walking surface and an inner limiting side surface connected vertically, the outer curve includes an outer walking surface and an outer limiting side surface connected vertically, the inner walking surface and the outer walking surface are arranged obliquely and parallel to each other, and the height of the outer walking surface is higher than that of the inner walking surface.

[0008] Preferably, the turning track realizes a 180° turn or a 90° turn.

[0009] Preferably, the angles between the inner and outer walking surfaces and the horizontal plane are between 4° and 8°.

[0010] Preferably, the inner curve and the outer curve have an upper shielding surface which is located above the inner walking surface and the outer walking surface with a gap therebetween and is parallel to them.

[0011] Preferably, the inner bend and the outer bend are connected by a group of U-shaped connecting plates, the two lower top corners of each of the U-shaped connecting plates are chamfered, and the group of U-shaped connecting plates are connected by connecting grooves at the two lower top corners.

[0012] Preferably, variable angle tracks are provided at both ends of the turning track for switching the axes of the running wheels on both sides of the sorting trolley between a horizontal and equal-height state and an inclined state with the inner running wheel lower and the outer running wheel higher.

[0013] Preferably, the variable angle track includes an inner transition rail and an outer transition rail, the inner transition rail includes an inner gradual walking surface and an inner gradual limiting side surface, the outer transition rail includes an outer gradual walking surface and an outer gradual limiting side surface, the inner gradual walking surface, the inner gradual limiting side surface, the outer gradual walking surface and the outer gradual limiting side surface satisfy that when the walking wheels walk at any position on the inner gradual walking surface and the inner gradual limiting side surface, the walking wheels are tangent to the inner gradual walking surface and the outer gradual walking surface, and the two limiting wheels are tangent to the inner gradual limiting side surface and the outer gradual limiting side surface.

[0014] Preferably, the inner transition rail and the outer transition rail are connected by a first U-shaped support plate and a second U-shaped support plate located at both ends of them, and the top edge and side edges of the first U-shaped support plate connected to the inner transition rail and the outer transition rail are perpendicular to the corresponding connection sides of the inner gradual walking surface, the inner gradual limiting side surface, the outer gradual walking surface and the outer gradual limiting side surface; the top edge and side edges of the second U-shaped support plate connected to the inner transition rail and the outer transition rail are perpendicular to the corresponding connection sides of the inner gradual walking surface, the inner gradual limiting side surface, the outer gradual walking surface and the outer gradual limiting side surface.

[0015] A track assembly comprises any of the above-mentioned turning tracks.

[0016] A sorting device comprises the track assembly as described above.

[0017] The advantages of the technical solution of this utility model are mainly reflected in:

[0018] The turning track of the utility model keeps the walking surfaces of the inner and outer curves for the walking wheels perpendicular to the limiting side surfaces against which the horizontal limiting wheels abut, thereby ensuring that the walking wheels and the horizontal limiting wheels can maintain a fully fitted state with the walking surfaces and the limiting side surfaces, avoiding local excessive wear and damage caused by overpressure of the horizontal limiting wheels, greatly extending the service life of the horizontal limiting wheels, and reducing the failure rate.

[0019] The turning angle of the turning track of the present invention can be set to 45° or 90° as needed, which can effectively meet the use requirements of waist-shaped track components or rounded rectangular track components and is more flexible in application.

[0020] The turning track of the utility model is connected to the horizontal track through the variable angle track, which can make the angle change of the sorting trolley smoother and smoother. At the same time, through the design of the track surface of the variable angle track, the walking wheels and the horizontal limiting wheels can always maintain a tangent state with the walking surface and the limiting surface, thereby ensuring the smoothness of movement, and is beneficial to protecting the walking wheels and the horizontal limiting wheels, thereby ensuring the reliability of equipment operation.

[0026] The objectives, advantages, and features of the present invention are illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of the application of the technical solutions of the present invention. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

[0027] In the description of the solution, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "back," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplification. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] The turning track disclosed by the utility model is described below in conjunction with the accompanying drawings. Figure 1As shown, the turning track 10 can achieve different turning angles according to the different structures of the track component. For example, when the track component is waist-shaped, the turning track 10 can achieve a 180° turn, and the turning track 10 can be a single track or multiple track segments connected in sequence; when the track component is a rounded rectangle or a rounded square, the turning track 10 can achieve a 90° turn. At this time, the turning track 10 can also be a single track or multiple track segments connected in sequence.

[0029] As attached Figure 2 As shown, the turning track 10 includes an inner curve 100 and an outer curve 200 arranged concentrically. The inner curve 100 includes an inner running surface 110 and an inner limiting side surface 120 connected vertically, and the outer curve 200 includes an outer running surface 210 and an outer limiting side surface 220 connected vertically. The inner running surface 110 and the outer running surface 210 are arranged obliquely and parallel to each other, and the height of the outer running surface 210 is higher than that of the inner running surface 110. The angle between the inner running surface 110 and the outer running surface 210 and the horizontal plane is between 4° and 8°, and more preferably between 5° and 7°.

[0030] The inner limiting side surface 120 can be connected to the upper part of the inner walking surface 110 or to the lower part of the inner walking surface 110. Preferably, the inner limiting side surface is vertically connected to the lower part of the inner walking surface 110 and is close to the side of the outer curve 200. Correspondingly, the inner walking surface 110 is the top surface of a load-bearing plate, and the inner limiting side surface 120 is the side of the limiting plate connected to the side of the load-bearing plate facing the outer curve 200. At the same time, the inner curve 100 has an upper shielding surface 130 that is located above and parallel to the inner walking surface 110. The upper shielding surface 130 is the lower surface of a shielding plate parallel to the load-bearing plate. The shielding plate and the limiting plate are connected by a connecting plate 140, and they form a U-shaped walking wheel groove as a whole.

[0031] The specific structure of the outer curved track 200 is the same as that of the inner and outer tracks, and will not be described in detail here.

[0032] As attached Figure 2 As shown, in order to ensure structural stability, the inner bend 100 and the outer bend 200 are connected by a group of U-shaped connecting plates 400, and the two support plates of the U-shaped connecting plates 400 are vertically connected to the outer sides of the bearing plate and the limit plate. At the same time, a group of reinforcing ribs can also be set between the bearing plate and the limit plate. The two lower top corners of each of the U-shaped connecting plates 400 are chamfered and a group of the U-shaped connecting plates 400 are connected by connecting grooves 500 at the two lower top corners.

[0033] As attached Figure 1As shown, in order to facilitate the smooth switching of the sorting trolley between the turning track 10 and the horizontal track 20, variable angle tracks 300 are provided at both ends of the turning track 10 for switching the axes of the running wheels 30 on both sides of the sorting trolley between a horizontal and equal-height state and an inclined state with the inner running wheel 30 low and the outer running wheel 30 high.

[0034] As attached Figure 3 -Attached Figure 5 As shown, the variable angle track 300 includes an inner transition rail 310 and an outer transition rail 320 , the inner transition rail 310 includes an inner gradually changing running surface 311 and an inner gradually changing limiting side surface 312 , and the outer transition rail 320 includes an outer gradually changing running surface 321 and an outer gradually changing limiting side surface 322 .

[0035] One end of the inner gradually changing running surface 311 and the inner gradually changing limiting side surface 312 is flush with and directly opposite the horizontal running surface and vertical limiting side surface of the inner rail of the horizontal rail 20, and their other ends are flush with and directly opposite the inner running surface 110 and inner limiting side surface 120 of the inner curve 100. The outer gradually changing running surface 321 and the outer gradually changing limiting side surface 322 are flush with and directly opposite the horizontal running surface and vertical limiting side surface of the outer rail of the horizontal rail 20, and their other ends are flush with and directly opposite the outer running surface 210 and outer limiting side surface 220 of the outer curve 200. The variation range of the inner gradually changing running surface 311 is smaller than the variation range of the outer gradually changing running surface 321. Thus, the inner gradual walking surface 311, the inner gradual limiting side surface 312, the outer gradual walking surface 321 and the outer gradual limiting side surface 322 satisfy that when the walking wheel 30 walks at any position on the inner gradual walking surface 311 and the inner gradual limiting side surface 312, the walking wheel 30 is tangent to the inner gradual walking surface 311 and the outer gradual limiting side surface 321, and the two limiting wheels 40 are tangent to the inner gradual limiting side surface 312 and the outer gradual limiting side surface 322.

[0036] The inner transition rail 310 and the outer transition rail 320 further include shielding surfaces that are flush with and directly opposite to the ends of the upper shielding surfaces of the horizontal rail 20 and the turning rail 10 , respectively.

[0037] At the same time, the inner transition rail 310 and the outer transition rail 320 are connected by a first U-shaped support plate 330 and a second U-shaped support plate 340 located at both ends of them. The top edge and side edges of the first U-shaped support plate 330 connected to the inner transition rail 310 and the outer transition rail 320 are perpendicular to the corresponding connection sides of the inner gradual walking surface 311, the inner gradual limiting side surface 312, the outer gradual walking surface 321 and the outer gradual limiting side surface 322; the top edge and side edges of the second U-shaped support plate 340 connected to the inner transition rail 310 and the outer transition rail 320 are perpendicular to the corresponding connection sides of the inner gradual walking surface 311, the inner gradual limiting side surface 312, the outer gradual walking surface 321 and the outer gradual limiting side surface 322.
