Technical Field

The invention relates to the technical field of logistics sorting system equipment, in particular to an unpowered roller sorting slideway.

Background

With the rapid development of the logistics automatic sorting industry in recent years, the related matched slide ways are more and more applied, and the technology is continuously improved. However, in the prior art, especially in the sorting of the slideways of various types of commercial super packages, the common slideway cannot solve the problem of the deviation of the falling lattice trajectories of the packages and the problem of the tipping of the packages due to the different speeds of the packages in the falling lattice process, so that the use of the chute is greatly influenced.

Existing ramps typically include both plate ramps and roller ramps. Wherein the plate system slide way is easy to damage the package because the common structure is a fold angle steering structure with distinct edges and corners formed by sheet metal, and the surface of the plate system slide way can not simultaneously meet the speed control of the packages with different packages, thereby generating the problem that the posture and the drop point position are not easy to control when the heavier packages drop. The unpowered roller slideway consists of a plurality of unpowered rollers, the slideway has a good bag falling effect of controlling speed for heavy goods, but cannot meet the requirement for lighter packages, and the main reason is that the interval between the rollers is too large, so that light packages, particularly file packages, soft packages of clothes and the like are easy to be stuck between the two rollers, and the packages are easy to be stuck and the operation of the whole slideway is possibly stopped.

Disclosure of Invention

The invention aims to provide an unpowered roller sorting slideway, which is used for solving the problems in the prior art, and can realize relatively stable track and slow speed of packages in the conveying process along the slideway and simultaneously avoid the problems of package turning, clamping stagnation and the like.

In order to realize the purpose of the invention, the invention at least adopts the following technical scheme:

the unpowered roller sorting slideway at least comprises a supporting leg for supporting, a first rail and a second rail which are arranged above the supporting leg and extend in a horizontal projection direction at intervals, and a wheel shaft which is distributed between the first rail and the second rail and is sleeved with a plurality of rollers at intervals, wherein the first rail and the second rail at least comprise a leading-in section which is arranged from upstream to downstream and extends linearly and a turning section which is bent around a curvature center, the second rail is positioned between the first rail and the curvature center in the horizontal projection direction, and in a section in the vertical direction, the vertical height is lower than that of the first rail, and a connecting line of the first rail and the second rail forms an included angle of theta degrees with the horizontal plane.

As a further preferable aspect of the present invention, a line connecting the upstream end and the downstream end of the first rail and the second rail forms an angle of θ ° with a horizontal plane.

As a further preferable technical scheme of the invention, the included angle theta is 6-10 degrees.

As a further preferable technical solution of the present invention, the axles located at the turning sections are in a divergent linear distribution radially outward from the curvature center.

As a further preferable technical scheme of the invention, the rollers on the adjacent wheel shafts are arranged in a staggered manner at intervals in sequence.

In a further preferred embodiment of the present invention, the first rail in the introduction section extends in an upstream direction less than the second rail, a connecting plate is connected between upstream end portions of the first rail and the second rail, and both ends of the wheel shaft located in the introduction section are connected to the connecting plate and the second rail, respectively.

As a further preferable aspect of the present invention, the first track and the second track further include a straight line section extending linearly from the downstream end of the introduction section to the upstream end of the turning section and/or from the downstream end of the turning section in the downstream direction.

As a further preferable technical solution of the present invention, the diameters of the rollers on the same axle are the same.

As a further preferable aspect of the present invention, a circumferential surface of the roller is parallel to a circumferential surface of the axle to which the roller is mounted.

The invention has the beneficial effects that:

1. the rollers and the wheel shafts provide the package above the rollers and the wheel shafts with an inclination which enables the package to move downwards automatically through the space arrangement of the first rail and the second rail and the arrangement of the inclination angle, and meanwhile, the transverse position and the track of the package along the moving direction basically do not deviate, and the downward moving speed is slow, so that the package cannot be turned out or dropped due to too fast movement;

2. the integral wheel shaft and the idler wheel are arranged in a spatial distribution manner, so that the packages passing through the upper part cannot fall off or be clamped into a gap, the small-sized and soft packages are more effectively adapted, and meanwhile, the effect of better keeping a moving track is achieved;

3. the inclined arrangement of the leading-in section enables the package entering the leading-in section to have a tendency of rotating, and meanwhile, the direction of the rotating tendency corresponds to the direction of the turning section, so that the package has good track keeping performance after entering the turning section, and has stable moving performance on the leading-in section and a straight line section.
